set custom lcd panel text on poweredge r720 supplier

I recently bought a pair of these servers to take over VMware duties from a pair of HP ProLiant DL380 G5 servers. Having had a few bad Dell experiences years ago I had stopped buying PowerEdge machines as I considered their design to be inferior (think PE1850) but I’m pleasantly surprised by these R710 machines.

In the server’s own BIOS options there is a Custom LCD field but entering text here and restarting doesn’t change the panel – it still just shows the Service Tag. Strangely, the iDRAC BIOS doesn’t offer you any control here at all, it just lists what the custom string currently is.

To make matters worse, I had accidentally got the desired result on one of the servers, but couldn’t get the second one configured. The answer lies with the buttons next to the LCD. Though you can view IP settings, temperature, power usage, etc., there is also a Setup option. With 48GB of RAM, each POST of the machine takes about 5 minutes so I had been too cautious to mess about with these options in case I undid some of my initial iDRAC config. I assumed that they would only provide a subset of the BIOS options. Wrong! You needto use the panel – even the iDRAC WebUI doesn’t seem to configure the LCD screen.

I haven"t found a complete reference of Dell"s proprietary IPMI commands, but according to the documentation I found here, the first invocation of ipmitool puts the supplied string into one of the display"s registers, and the second one flips the display buffer to actually show this.

You can change it in BIOS Setup F2 by going to Embedded Server Management and setting Front-Panel LCD Options to User-Defined String, then goin gto User-Defined LCD String to set the string.

You can also change it from the OS using OMSA (OpenManage Server Administrator by going to System, Main System Chassis, Front Panel (sub tab), and set LCD Line to Custom.

On Dell hardware, you have the option of configuring the Forge Appliance LCD, a small readout on the computer’s front panel. Use these steps to configure the LCD display for Forge:

The Dell PowerEdge R720 12th Generation is a 2-socket, 2U server that features the Intel Xeon E5-2600 processor family and supports up to 768GB of DDR3 memory. Dell offers the R720 in various backplane configurations with up to 16 2.5-inch internal hard drives or 8 3.5-inch drives. A new optional feature though, designed to take the performance compute server market by storm, are 4 hot-plug front-access 2.5-inch Express Flash PCIe SSDs geared for high throughput and incredibly low latency. The PowerEdge R720’s Express Flash connectivity makes it unique among servers of its class, and is one of the reasons we have added two R720 units to the lab.

It’s not just storage technology itself that is a moving target – other critical components of enterprise storage infrastructure like interconnects and compute platforms are also continually evolving. Compute servers are not our primary focus, but performance and scalability differences between similarly-spec’d servers from different manufacturers or different generations from the same manufacturer can have important consequences for storage performance. It is also important to understand how factors like chassis construction and layout will affect long-term routine maintenance of a server.

StorageReview’s two new PowerEdge R720 servers feature Xeon E5-2640 2.50GHz processors with 15M cache and 7 PCIe slots to power real-world enterprise testing environments as well as see how storage devices perform when used in conjunction with compute servers from various manufacturers. One of our R720 servers is configured with 8 2.5-inch SFF internal drive bays and 4 front-accessible Express Flash bays. The other R720 features 16 2.5-inch SFF internal drive bays. Our review will focus on the PowerEdge R720 with Express Flash, noting key differences between the two when appropriate. The PowerEdge R720 is also available with a chassis configured for 8 3.5-inch LFF drives.

Availability: High-efficiency, hot-plug, redundant power supplies; hot-plug drive bays; TPM; dual internal SD support; hot-plug redundant fan; optional bezel; luggage-tag; ECC memory, interactive LCD screen; extended thermal support; ENERGY STAR® compliant, extended power range; switch agnostic partitioning (SWAP)

The most notable option offered by the PowerEdge R720 is a chassis that supports up to four front-access 2.5-inch PCIe Express Flash drives. The PowerEdge R720 uses a x16 PCIe breakout board for Express Flash connectivity, each drive requiring four lanes. Express Flash storage can be configured as cache or as a primary storage, offering lower latency and much greater performance than an SSD connected via SAS or SATA. Express Flash drives supplied in our R720 are 2.5-inch Micron P320h models, which use 34nm SLC NAND and are engineered for write-heavy applications. Dell warrants the lifetime of Express Flash drives in terms of bytes written; current 175GB and 350GB models offer 12.5 and 25 petabytes of drive writes, respectively. Dell software management applications can be configured to notify the server administrator when these wear limits are nearing. Our Express Flash R720 shipped with four 350GB drives.

Express Flash PCIe SSDs support orderly insertion, when a drive is added to a running system in a bay where an Express Flash drive has not been previously inserted since booting. Express Flash also supports orderly removal, where the system is notified prior to drive removal, and orderly swap, when a drive can be replaced with prior system notification. PowerEdge R720 servers also support Dell’s CacheCade technology, which provides automated storage tiering on SSDs when using PERC H810 and H710P controllers. The R720 can employ redundant failsafe hypervisors, and can be used as part of Dell’s Virtual Integrated System (VIS) solution.

The PowerEdge R720 supports Dell’s Select Network Adapters daughter cards to house the server’s LOM subsystem without requiring a PCIe slot. Network connectivity options for the R720 include 1000 Base-T, 10Gb Base-T, and 10Gb SFP+ interfaces from Intel and Broadcom. It can be configured to operate with a single 495W, 750W, or 1100W AC power supply module, or can be equipped with a redundant power supply. As a top-tier option, Dell offers an 1100W DC power supply for the PowerEdge R720. In the default redundant configuration, power is supplied equally from both supplies, but may be reconfigured via iDRAC to enable a hot spare feature which switches one power supply to sleep unless needed.

The R720 can support up to four passively-cooled graphics processing units (GPU) to accelerate virtual desktop infrastructure and high performance computing applications. Breaking it down by power capabilities, the R720 can support two 300W, full-length, double-wide internal GPUs or up to four 150W, full-length, single-wide GPUs. Each GPU can support up to 6GB of dedicated GDDR5 memory. Actively-cooled GPU cards are not supported as they interfere with and are not designed for forced-air cooling inside a server. The R720 can also connect to PowerEdge C410x external GPUs through a host interface card (HIC) with an iPass cable. Both the NVIDIA and Dell x16 HICs require the R720s single x16 PCIe slot to support up to four external GPUs.

As with StorageReview’s Gen8 HP ProLiant DL380p, the R720 supports up to 768GB of memory across 24 DIMMs when equipped with dual-processors. Each processor has 4 memory channels, each channel supporting up to 3 DIMMs. In addition to supporting unbuffered DIMMs (UDIMMs) and registered DIMMs (RDIMMs), the R720 supports load reduced DIMMs (LRDIMMs). In our configurations Dell supplied 24 8GB RDIMMs to populate all memory channels inside the R720 providing 192GB of system memory.

12th generation PowerEdge servers are part of Dell’s OpenManage platform, built around the Integrated Dell Remote Access Controller 7 (iDRAC7) with Lifecycle Controller, which provides agent-based and agent-free management. To integrate with agent-based solutions, Dell provides the OpenManage Server Administration (OMSA) which provides one-to-one systems management with a CLI interface or Web-based GUI. iDRAC7 can also provide remote access to the system whether or not there is an operating system installed. Through the iDRAC7 interface, users can quickly learn vital system information in many categories including storage, thermals, power and others. When first logged in to, iDRAC7 presents the user with health stats in all categories, as well as a preview of the iKVM.

Drilling down into the storage category, users can view information on the current disk configuration, as well as individual drive stats. Shown below is the RAID10 disk array we configured utilizing eight 300GB Seagate Cheetah 15K.3 enterprise hard drives connected through the Dell PERC H710p on-board RAID controller. Through this screen users would be able to quickly find out information about a drive failure remotely as well as narrow it down to which slot has the defective drive.

For remote system access where Remote Desktop or SSH might not be feasible, iDRAC7 includes a virtual console that gives users access to the system through a standard web browser with JAVA. This window also has useful features for remotely triggering power controls to restart a frozen system or even turn on a system without local access. Users can also mount local media to be accessible by the remote system, or map ISOs to quickly provision systems over the network.

The PowerEdge R720 debuts a new PowerEdge chassis design intended to support greater scalability compared to 11th generation PowerEdge servers, with an increased number of DIMMs, PCIe slots, and hard drives. Also unique to the 12th generation R720 are the four ExpressFlash slots, which currently support 175GB and 350GB Micron RealSSD P320h PCIe SSDs. When we reviewed the HHHL Micron P320h last year, we found it to offer class-leading performance.

The front of the server features a power button and indicator, recessed non-maskable interrupt (NMI) button to troubleshoot software and device driver errors, two USB connectors, Dell’s vFlash SD media reader (activated with iDRAC7), video connector, and a simple LCD control panel interface for local management. The vFlash media SD card reader is used for configuration, scripts, imaging, and other local management tasks. Dell’s 12th generation PowerEdge servers feature a model-specific QR code that links to video overviews of system internals and externals, task-oriented videos and installation wizards, reference materials, LCD diagnostics, and an electrical overview. This code appears several places on the chassis.

The rear of the unit offers access to up to two hot-plug power supplies and associated indicators, network connectivity via Dell’s Select Network Adapter family, two USB ports, iDRAC7 Enterprise port, video connector, and serial connector. Also visible are the available PCIe slots, rear carrying handle, as well as the two redundant 1,100 watt power supplies.

The R720 supports ReadyRails II sliding rails for tool-less mounting in 4-post racks with square or unthreaded round holes, or tooled mounting in 4-post threaded hole racks. The R720 is also compatible with ReadyRails static rails for tool-less mounting in 4-post racks with square or unthreaded round holes or tooled mounting in 4-post threaded as well as 2-post Telco racks.

For improved cable management, Dell offers a toolless cable management arm compatible with the PowerEdge R720. In our lab evaluation, the sliding ReadyRails II were quick to clip into position in our Eaton S-Series Rack, and offered a secure fit with minimal slack.

To install the R720 in the rails, users hold the server by the front and the rear carrying handle and carefully lower it into the extended rails while aligning the mounting pins with their appropriate slots. We found this process to be very intuitive and easy to nail on the first try, which quickly sped up the time required to get the server into production status.

The PowerEdge R720 supports hot-swappable cooling fans in an N+1 configuration, allowing a technician to replace any one fan at a time. Supporting newer environmental conditions, the R720 also incorporates Dell’s Fresh Air cooling design, allowing the server to operate above 35°C/95°F to reduce power consumption and related cooling expenses. This is also beneficial should a user want to deploy the R720 outside of traditional datacenter environments, where temperatures may be more variable.

When it comes to servicing components, the R720 can be operated temporarily without one of its cooling fans, allowing hot-swap replacement. The design of the cooling fan assembly makes it straightforward to remove and replace individual fans or the entire assembly. When replacing an individual fan, you grip the fan’s release button and lift the fan out of position, which also releases the power connection in one easy step. For more expansive repairs requiring the removal of the entire cooling assembly, users can lift latches on both sides of the server and lift out the entire unit in one piece.

When it comes to managing airflow, Dell allows the user to select the appropriate cooling mode for that specific environment. These user-selectable modes are invaluable to servers with additional equipment, such as PCIe Application Accelerators, which can overheat when certain automatic cooling modes. This happens because the server incorrectly throttles fan speeds based on chassis temperatures while local temps of the AA are still high. In these cases, being able to modify the cooling parameters to run faster than normal can allow better performance and increase reliability.

Utilizing our high-I/O FIO synthetic benchmarks we stressed the four Express Flash PCIe SSDs with a chassis inlet temperature of 27C. We found PCIe SSD temperatures dropped from 62C to 49C by switching the cooling profile from Auto to Maximum performance, and enabling the High Fan Speed Offset. To put it another way, without having that adjustment the PCIe SSDs would have been operating 26.5% hotter, which might affect long-term reliability. The downside is this changes the R720’s acoustic profile (increased fan noise) but given their production environments, datacenter noise levels for high-performance servers aren’t greatly impacted. In the tier-one server market right now, HP allows users to customize the fan speeds through the BIOS in the ProLiant DL380p Gen8 although Lenovo with their ThinkServer RD630 does not.

Dell goes to great lengths to optimize the new 12th generation PowerEdge R720 for power efficiency. For the R720, Dell offers four AC 100-240v PSUs, ranging from 495W up to 1,100W. By gearing the known load to a given power supply, users can achieve up to 96% efficiency with some models, which helps to lower overall power and thermal demands inside a datacenter. In this same category, HP offers power supplies ranging from 460 to 1,200 watts with their most efficient models rated at 94% for the DL380p Gen8, while Lenovo offers just one 800W 80Plus Gold option for their RD630.

Another way the Dell PowerEdge R720 can reduce power consumption inside a datacenter is by capping the system at a user-defined limit. When this limit is reached, the processors are throttled to lower system power usage until the target is reached. This can be useful when introducing new servers into an environment that is designed around strict power or thermal limits.

After the R720 has been customized for a specific environment by choosing the best PSU to fit the requirements and adjusting the power cap policy to fit the datacenter needs, Dell offers excellent monitoring tools for tracking power usage through iDRAC7.

When it comes to describing the performance advantage of front-mounted hot-swappable PCIe storage, the paradigm shift of transitioning from rotating media to 2.5″ SATA or SAS SSDs comes to mind. Random I/O and sequential bandwidth is on a much higher level, which would require many of the industry’s fastest SAS SSDs in RAID to match the performance of one Express Flash PCIe SSD… let alone four of them.

We’ve included a quick performance comparison of four Express Flash PCIe SSDs up against eight 15k SAS HDDs and one Smart Optimus Enterprise SAS SSD in our 8k 70/30 synthetic benchmark. We chose the SMART Optimus for this comparison, since at the time of this review it offered the highest 8k 70/30 performance in the SAS/SATA category. And note, this is a small tease of what’s to come, a detailed storage performance breakdown will take place in a second review highlighting the Express Flash technology.

Breaking it down by the numbers, at peak performance with a load of 16T/16Q per drive/array, the Dell Express Flash solution offered 467,644 IOPS, the SMART Optimus measured 41,586 IOPS, and the eight-drive 15K SAS RAID10 array came in with 4,617 IOPS. To match the performance of four Express Flash SSDs, you’d need 12 of the industry’s fastest SAS SSDs, or more than 800 15K SAS HDDs in RAID. In either of those situations, even if you were able to match the performance by scaling out, you’d lose the benefits of reliability, power consumption, and footprint, since you’d be dramatically increasing the components inside (or outside) the system.

With Dell’s Express Flash layout on the PowerEdge R720, you can still have your cake and eat it too. You don’t have to trade capacity for performance, since you still keep eight SFF bays on the front of the chassis to populate with your favorite SAS or SATA drives. You also gain an edge over other compute server platforms, since four x4 PCIe devices only consume one x16 slot. To exceed the performance of four Express Flash SSDs, you’d need to install three x8 HHHL Micron P320h cards, taking up three out of the seven available slots. That performance-density gives Dell a distinct advantage over the HP ProLiant DL380p Gen8 (6 PCIe 3.0 slots) or Lenovo ThinkServer RD630 (5 PCIe 3.0 slots), which would have to scale out Application Accelerators to match a four-drive Express Flash configuration, taking up valuable PCI-Express slots where Dell needs just one x16 slot.

The Dell PowerEdge R720 12th Generation marks more than just a progressive step in mainstream 2U server technology. Dell has been the first to embrace front-mounted, hot-swappable PCIe storage technology in the new R720. For enterprise users who want maximum performance with all the serviceability benefits of traditional SFF drives, the new Express Flash design is a savior for so many reasons. As we’ve seen in our cursory performance look, the Micron Express Flash drives simply dominate the best in class 15K and SAS SSD options in the market today, while still providing a total capacity of up to 1.4TB in the four bays. Should additional storage be needed, users can deploy SFF hard drives in capacities up to 1.2TB now that provide a great backstop to the flash drives in caching use cases and anywhere else where a platter tier makes sense. And because the Express Flash drives in aggregate only take up a single PCIe slot, there’s still plenty of expandability in the 6 available risers for additional PCIe storage if needed. As noted, we’ll dive more into storage performance within the R720 specifically in subsequent content.

While we certainly appreciate the storage aspects of the R720, there are a ton of other reasons to be excited about the platform as well including management, hardware design and thermal controls. The R720 provides an intuitive package dubbed iDRAC7 for remotely monitoring and managing the server, while providing a landing page with every health stat readily available. Turning to hardware design, the R720 packs plenty of mounting and serviceability options, where almost all frequently accessed components are easy to swap out if servicing is required. For cooling and power needs, Dell offers a wide range of PSU options to tailor the system for the best efficiency. Dell then takes things a step further by allowing users to adjust the cooling profiles for high-end devices like PCIe storage that require higher airflow requirements than the automatic mode can provide. Overall buyers can effectively use the Dell PowerEdge R720 as a blank slate, customizing it exactly for their needs, versus trying to shoehorn in an option-fixed model that might not be best in all situations.

As we compare the Dell PowerEdge R720 to other 2U servers on the market that we have reviewed previously from HP and Lenovo, one point is very clear; the R720 currently offers the fastest storage platform on the market in a 2U form factor. While you could try to match it by scaling out with multiple Application Accelerators in other server platforms, you’d lose potentially valuable PCIe real-estate. Dell’s thoughtful design is evident throughout, and the Express Flash components are even upgradable as newer iterations of that technology come out, like NVM Express.

The Dell PowerEdge R720 12th Generation server is not only well-designed with loads of great management features, it’s also the best performing server on the market in this class. Sure, it’s great as a garden variety standard compute server, but with Express Flash technology the R720 really shines, easily lapping all others. Dell has put the definitive stake in the ground by adopting new technology, giving their users a best of breed solution.

Pie charts show proportions of the whole By Wendy Russell Wendy Russell Writer Brock University Former Lifewire writer Wendy Russell is an experienced teacher specializing in live communications, graphics design, and PowerPoint software. lifewire"s editorial guidelines Updated on May 26, 2020 Tweet Share Email Tweet Share Email

In This Article Expand Jump to a Section Create a Pie Chart Choose a Style The Generic Pie Chart and Data Edit the Data The Updated Pie Chart Create a pie chart in PowerPoint to visually demonstrate proportions of a whole. After you"ve created the basic chart, adjust the chart"s data, alter its style, and update it on the fly. Information in this article applies to PowerPoint 2019, 2016, and 2013; PowerPoint for Microsoft 365; and PowerPoint for Mac.

Create a Pie Chart in PowerPoint Begin by adding a new slide using the Title and Content slide layout. Then, select the Insert Chart icon (it"s the middle icon on the top row of the group of six icons shown in the body of the slide layout). Another way to add a pie chart is to choose a blank slide in your presentation and select Insert > Chart.

Choose a Pie Chart Style In the Insert Chart dialog box, select Pie and choose a pie chart style. There are several style of pie charts. Options include

flat pie shapes, 3D pie shapes, and pie charts with exploded pieces. Select OK after you have made your selection. The pie chart styles and colors can be changed after the chart is created.

The Generic Pie Chart and Data When you create a pie chart on a PowerPoint slide, the basic chart appears on the slide and the chart data appears in a worksheet window. If you don"t see the worksheet window, select the chart and select Chart Tools Design > Edit Data. You"ll use the worksheet window to enter data for the pie chart by replacing the default data.

Edit the Pie Chart Data Pie charts display comparative types of data, such as percentage figures for how much each of your monthly household expenses takes from your income. However, pie charts display one type of data, unlike column charts or line charts. To edit the data in the worksheet window: Select the worksheet window to make it the active window. Edit the heading of the column in the generic data to reflect your own information. Edit the row headings in the generic data to reflect your own information. The chart updates to reflect your changes. To add new data rows, drag a corner handle of the highlighted data set.

Updated Pie Chart Reflects New Data After you change the generic data to your own specific data, the information is immediately reflected in the pie chart. Add a title for your slide into the text placeholder at the top of the slide. How to Make a Gantt Chart in PowerPoint Was this page

Key Takeaways Instagram is encouraging users to sign up for multiple accounts.These accounts can be linked, so you don’t have to log out to switch between them.Facebook may count all these sign-ups as new users. SHTTEFAN / Unsplash A cynical person might say Instagram"s multiple-account promotion is all about padding its user numbers, but it could actually be useful. Instagram has been encouraging users to sign up for more accounts for a while now. If you do, you can either link that account to the

one(s) you have already, or you can make it a separate account. Facebook wins here because it gets to add all those extra signups to its new-users metric. But multiple accounts might be a good thing for users, too. "As an author/speaker," Christine Eberle told Lifewire via email, "I use two Instagram accounts: one personal, one professional. My professional followers don"t need to see all those pictures of dogs, meals, and sunrises!"

Keep It Simple If you"ve been using Instagram for a while, perhaps you follow many people. A new account might seem like a fresh start, and Instagram is indeed billing it that way. One of its sign-up notifications suggests you can "keep up with a smaller group of friends," for example. Or perhaps you might like one account for work and one for personal use. Or you"re sick of following some folks but don"t want them to see you"ve unfollowed them. I use two Instagram accounts: one personal, one professional. There are many good reasons to create a second or third Instagram account. And because it’s easy to switch between them without logging out of one account and back into another, you can almost treat your accounts like separate tabs of the app.

Keep It Professional Professionals can benefit, too. Marketers, PR people, anyone who has to follow lots of people—can benefit from some account segregation. For example, one respondent to my requests for comment, Dymphe Mensink, a travel content creator, told me she uses two accounts, one for personal use and

another for business. "Besides my main account where I post all kinds of travel photos and videos, I have a separate account for selling photo presets," says Mensink. "An extra account allows me to refer to that account in my posts by tagging, which makes it easier for my followers to find my presets, which is better for selling them." ian dooley / Unsplash Designer, UX expert, and multiple-Instagram-account user Geoffrey Crofte agrees: "It"s well known in the industry of video, shorts, and imagery that having a one-topic account is the best way to grow your followers," Crofte told Lifewire via email. "People now have two choices: dedicate their own account to a topic, or create a new account for it."

What s in It for Facebook Facebook, aka Meta, the owner of Facebook, makes its billions from targeted ads. And few ad platforms offer better targeting than Instagram—based purely on using it and knowing how scarily tempting those ads are. We’ve already mentioned that having more new user accounts is a good thing for a company that measures its success in terms of the size of its user base. But could these accounts also allow for even more effective and targeted advertising? Instagram "Because [separate accounts] essentially encourages niching down and laser-focusing content to easily-defined user clusters, it can make targeted advertising easier, which is a good thing as far as Facebook is concerned," tracking company founder Charles Helms told Lifewire via

email. "For [Facebook parent company] Meta, this means one more place to display ads and a second hit at the same set of eyes," marketing strategist Ashley-Anne Schmidt told Lifewire via email. But really, everybody seems to win here. Instagram users can better separate their areas of interest and create more private accounts to share with a subset of their regular followers. Businesses can better control their marketing, and Facebook gets to make yet more money. Overall, then, multiple accounts look like a good thing. Was this page helpful? Thanks for letting us know!

Need for Speed Hot Pursuit Remastered: 4K 60fps tested on PS5 and Series X Eurogamer.net If you click on a link and make a purchase we may receive a small commission. Read our editorial policy. Need for Speed Hot Pursuit Remastered: 4K 60fps tested on PS5 and Series X

The upgrade isn"t all it should be - and there"s no boost for Series S. Face-off by Richard Leadbetter Technology Editor, Digital Foundry Additional contributions by John Linneman Updated on 3 Mar 2021 49 comments With the arrival of the new wave of consoles, we didn"t have the time to fully check out Need for Speed Hot Pursuit Remastered when it launched, but the Criterion masterpiece is especially deserving of our focus now as support has been added for the nex-gen consoles, opening the door to a 4K experience running at 60 frames per second. More than that, in the wake of the news that Criterion"s new Need for Speed title has been delayed, it"s also an opportunity to reflect on an astonishing run of iconic racing games from the Guildford-based developer. It"s something I was discussing with John Linneman recently: what exactly is peak Criterion? Some might say it"s Need for Speed Hot Pursuit - a game that radically rebooted the franchise, bringing over the best of Burnout but respecting the core DNA of what made the original NFS titles so great. And then there was Autolog, of course, a remarkably successful attempt to meld social networking into a video game. But despite some remarkable coding resulting in input latency

that matched or even beat some 60fps games, Hot Pursuit was a 30fps title in an era where 60fps was Criterion"s hallmark. So maybe it"s actually Burnout Paradise that"s peak Criterion? But what about the incredible Burnout 3: Takedown? Or maybe the purist"s favourite, Burnout 2: Point of Impact? Perhaps it"s simply enough to say that from the arrival of Burnout 2 all the way through to Need for Speed Hot Pursuit, Criterion was the undisputed master of the racing genre, with every game a must-buy - and in returning to what was the last truly great Criterion racing offering, it"s very much business as usual. Yes, Hot Pursuit hasn"t radically evolved visually from its PC rendition and despite running at higher resolutions and (on select formats at least) higher frame-rates than the original console versions, it"s very much a game of its era. But the bottom line is that the game still runs beautifully, the handling is sublime and the concept is to-the-point, immediate and brilliant. Perhaps best of all is the vista-like presentation: the promise of an open road that stretches far into the distance. And yes, the resolution boost definitely helps there. Watch on YouTube John Linneman and Rich Leadbetter share their experiences of Hot Pursuit Remastered on the new wave of consoles. It"s interesting to see how Stellar Entertainment has handled the remaster and its translation to the various platforms. Hot Pursuit was fundamentally a 30fps game and so are most of the ports. PlayStation 4, Xbox One and Nintendo

Switch all target 1080p30 (with 720p30 delivered on the mobile rendition). Only PlayStation 4 Pro and Xbox One X had the option to improve frame-rate, with the choice offered between 4K30 and 1080p60 gaming. The recent upgrade isn"t actually a patch specifically targeting the new machines: a new Maximum quality mode simply removes the frame-rate cap from the existing Pro and One X versions, allowing the inherent back-compat support in the brand new machines to kick in, propelling us to 60 frames per second. So yes, the modes targeting PS5 and Series X are also available on the last-gen enhanced machines too. It"s not so much "back compat plus" as such, more a simple mechanism to allow the existing game to get a measurable performance boost without the potential requirement to migrate across to a later, cross-gen enabled SDK. What this does mean is bad news for Xbox Series S? Anchored down by the Xbox One S codepath, there are no extra modes added, so 1080p30 is the best you"re going to get. Despite delivering a relatively huge increase in GPU power, and being easily capable of delivering 1080p at 60fps, there is no upgrade for Series S users - and that"s a massive shame. And it"s actually quite interesting to see that the new Maximum mode sees PS4 Pro at 4K unlocked typically running in the mid-40s, while Xbox One X by default is within touching distance of 4K60 in many scenarios - but what stands out from the performance analysis that running unlocked, Pro and One X are perhaps much more closer in output

than the spec differential between the two systems would suggest. Unlocking frame-rate at 4K works out fine for PS5, but owing to some software-related problem, Series X encounters performance issues in one specific area of the map and is less stable overall. In theory at least, moving the same code to PS5 and Xbox Series X should deliver a foregone conclusion then: with a 2x increase in GPU performance minimum, both should lock to 4K at 60fps with plenty of horsepower to spare. And that"s definitely the case with PlayStation 5, which simply powers through at full frame-rate across our testing. However, we did encounter a specific problem area in the map on the Xbox version, which can see performance drop to the low 40s - and indeed the low 30s on Xbox One X. It only seems to be this one specific area on the map, near the coast, but because Hot Pursuit"s tracks are all built around a single world, you do find yourself revisiting the same location fairly frequently and thus encountering the same performance drop. It"s flawless on PlayStation 5, but clearly a problem on the Xbox side... and it does seem to be a GPU issue as the 1080p60 mode is still available and works fine there. To be clear though, it"s very clearly a software issue - after all, Hot Pursuit Remastered does seem to be based primarily on the PC original, which was exceptionally well put together back in the day. So, ultimately, a game that should have a large amount of overhead on the new machines (based on their unlocked behaviour on the

last-gen enhanced consoles) should deliver a flawless experience on their shiny new equivalents. That is the case with PlayStation 5, but the drop is significant enough on Xbox Series X that we would hope to see EA revisit Hot Pursuit Remastered to iron out the problem there - and quite why there are any issues at all is a bit baffling. Meanwhile, the lack of Series S upgrades is also disappointing - there"s no technical reason whatsoever why Microsoft"s junior next generation console shouldn"t be delivering 60fps. Enhancements like crossplay are welcome, but ultimately, the 30fps cap was the only real technological limitation that held back the original game and at full frame-rate, one of the best racing games ever made just feels sublime. Years on from its initial release, Hot Pursuit is still an absolute gem. Will you support the Digital Foundry team?

Preventing Coronavirus Exposure When You Have Psoriasis and EczemaCaring for your skin these days is challenging, but you can manage these conditions and still protect yourself from COVID-19.

By Howard ChangFor The Itch to Beat PsoriasisApril 6, 2020Everyday Health BlogsFact-CheckedCreams and ointments can help moisturize hands and reduce irritation from frequent hand-washing.iStockLiving with psoriasis and atopic dermatitis, or eczema, means I’m always thinking twice about what might exacerbate these skin conditions. I need to especially consider what in my environment might trigger itchiness or rashes. Now, as we’re all faced with the novel coronavirus, I’m even more vigilant about how practices such as frequent hand-washing and disinfecting may affect my health.

Take, for example, a recent shopping trip to my local Costco. I grabbed a shopping cart before entering, much like any other time. On this visit, though, a bleach wipe container sat on a table inside the door. I dutifully took a wipe to disinfect the cart handle. Then I looked at my hands, wondering if I should wipe them too and thinking about how it might irritate my skin.

The Centers for Disease Control and Prevention’s (CDC) website lists ways to protect yourself from exposure to the coronavirus. I’m already at a higher risk for

The National Psoriasis Foundation Medical Board’s recommendations for those with psoriatic disease state that “patients with severe disease, those on potentially immunosuppressive therapies and those presenting with comorbid conditions may be at a higher risk for infection.” They recommend patients contact their healthcare provider’s office with any concerns related to treatments such as biologics.

Even if you are not in a higher risk group for COVID-19, the public health message is for everyone to follow measures to stop the spread of the coronavirus.

A repeated message to stop the spread is to clean hands frequently, ideally with soap for at least 20 seconds. If soap is not available, then hand sanitizer with at least 60 percent alcohol serves as a replacement. Unfortunately, frequently cleaning my hands dries them out. Soaps and hand sanitizers can contain perfumes that my skin reacts to as well.

The American Academy of Dermatology Association (AAD) recommends that you leave some water on your hands when drying them and apply hand cream or ointment while they’re still damp. The AAD also points out that dermatologists recommend using a cream or ointment that contains mineral oil or petrolatum and says it’s “fragrance-free” and “dye-free.”

Another CDC guideline is to avoid touching your eyes, nose, and mouth, because they can serve as pathways for the virus to enter the lungs and throat. Germs can spread when you touch a contaminated surface, such as a doorknob or countertop, and then touch your face.

Touching the face is something people often do without even noticing. A study published in February 2015 in the Journal of Infection Control observed that students touched their faces 23 times an hour, with 44 percent of touches involving a mucous membrane. With rashes on my face, including my eyelids, it can be very difficult for me not to touch my face.

On their website, the National Eczema Association responded to questions related to the coronavirus, including how to avoid touching facial eczema. Their first recommendation is to practice distraction techniques such as “playing handheld video games, arts and crafts, or playing a musical instrument.”

They also recommend using “competing responses,” which replace one behavior with another. For example, every time I want to touch my face, I might snap my fingers or touch my leg instead. They conclude, “If you do need to deliberately touch your face, wash your hands first; avoid the nose, eyes and mouth; and perhaps use a clean cloth or Kleenex.”

Since psoriasis and eczema on my face is an ongoing issue, I follow my facial skin treatments carefully to reduce irritation and itchiness. Contact your healthcare provider or dermatologist if

Fortunately, we live in an age where people connect through a variety of electronic means, such as video and text chat, virtual communities, or online games and activities. I felt uplifted and encouraged after recently joining a church group on a video chat. If you are sheltering at home, you may have more time to catch up with old friends and family.

Virtual connections can even help you communicate with your doctor. The NPF Medical Board, for example, recommends “telehealth appointments whenever possible for routine visits during the pandemic.” Both my daughters successfully used telehealth for their r
