This will flip the skin around to use the old Win7 time-based counters, and you'll see it now acts like your other CPU skins.Īn easy way to tell what any skin is using without digging into the code is to max out your CPU and look to see if the performance exceeds 100%. If you want to see the difference, open the CPU Meter Settings skin (click the wrench icon in the upper right corner) and check the option "Use Legacy Mode". This is why the Gadgets CPU Meter matches Windows 11's Task Manager, it uses the new utility performance counters. And Turbo Boost drives the processor above 100% of its nominal speed, and allows the processor to exceed 100% capacity.Īny Rainmeter skin that uses CPU measures, or UsageMonitor measures that use the CPU alias, will not report CPU performance accurately (or at least, not the same way Task Manager or Resource Monitor does). With the redesigned Task Manager, the first processor is shown to be running at 50% capacity, whereas the second processor is shown to be running at 100% capacity. Both appear to be doing the same amount of work: 100% of their capacity. Before this change, under the time-based performance counters (used in Windows 7 Task Manager), those two processors clocked differently. A processor that's running 50% of the time and clocked down to 50% frequency performs only half the work of a processor that's running 100% of the time at 100% frequency. This change was intended to provide a more accurate representation of how much work the system is handling, and the utility counters do just that. The utility performance counters take into account the processor performance state and Turbo Boost-based enhancements to measure and normalize the work that's being done by the CPU. The old time-based performance counters measure the percentage of time that the processor is busy, whereas the new utility performance counters measure how much work the processor actually performs. The difference between the two counter types concerns how they measure the actual work that the processor performs. (Windows Resource Monitor will show values over 100%.) Task Manager's CPU Performance tab will truncate (or clamp) CPU utilization values to 100%.Rainmeter's CPU measure and the UsageMonitor plugin with the CPU alias both use the Windows 7-style Processor > % Processor Time counter.The old performance counters, Processor > % Processor Time and Processor > % Privileged Time still exist, and were used by Task Manager in Windows 7 and earlier. Microsoft created new performance counters, Processor Information > % Processor Utility and Processor Information > % Privileged Utility that attempt to better report the work a CPU is doing starting with Windows 8, Task Manager now uses these counters. This change affects the way that CPU utilization is computed. Starting with Windows 8, a change was made to the way that Task Manager and Performance Monitor report CPU utilization. (This does not mean your observations about Win11 22H2 aren't correct, they may be true too.) If you want the long version, here it is: With all that said, I do need point out that the CPU utilization you see in Windows Task manager has not matched Rainmeter since approximately Windows 8. That is why things appear and disappear unfortunately, there's nothing I can do about that, it is a Rainmeter issue.) (The Top CPU Meter does bounce around a lot because Rainmeter does not report processes that use less than 0.1% CPU. What I can say is that all this usage info is coming from Windows itself, so Rainmeter is only telling you what Windows says. It may have something to do with Microsoft tweaking the way the thread scheduler works for the newer hybrid CPUs (p-cores vs. I can't say for sure why you see a difference between Win11 21H2 and Win11 22H2. How come Gadgets cpu usage works but not Rainformers? Worked perfectly on Windows 11 21H2. And the CPU usage in the top CPU rainmeter on both Gadgets and Rainformer show the incorrect CPU usage for processes. However the top CPU rainmeter from Gadgets seems to show the exact same symptoms as Rainformer under 22H2, it only shows a few process for a few seconds, then more processes the next second and the other second just two process for example. The Gadgets CPU-meter seems to be accurate on Windows 11 22H2 as below screenshots when I compare it to Rainformer and Task Manager. Beeta wrote: ↑ September 22nd, 2022, 6:14 am
