thanks to youtube algorithm they give me this to recomandated,so after years of tweks and settings,is one of the best so far that helped,ive done this last night,so far its stable ( dont have high hopes) give it a trie! also there are more things in there to play with!

Rather than posting a video link, can you explain (or at least summarize) exactly what steps you took?

UPDATE:

So in the video, they suggest changing the (hidden by default) "Processor performance time check interval" setting in Windows' Power Management from the default (15ms) to something much higher (e.g. 2000ms, the upper-limit is 5000ms BTW).

Their argument is that when set to the default (15ms), it causes more CPU/hardware interrupts than at lower intervals (66/second at 15ms vs 2-every-second at 2000ms) - and that there is no reason for the computer doing a CPU performance measurement on a desktop on AC power - so by using a longer interval you prevent needles CPU interrupts.

...while I agree with their logic, I'm not persuaded by that argument: I think they're drastically overstating the actual performance impact (66 interrupts/second isn't much in the grand scheme of things: a Windows 10 machine today will process 10,000 interrupts/second) and at no point in the video did they show or demonstrate any quantiative performance increase, nor decrease in "latency"/"lag" (however they define it) - all they pointed to was seeing fewer interrupts being recorded by the xperf trace (well of course...).

But if you want to try it out, then this can be done by running this batch file in an elevated command-prompt window:
I'm in the process of evaluating if this helps solve my own imprecise/floaty-mouse-pointer issue (for me, the problem is tempramental and varies day-by-day, and since this morning my computer has had a "good" days, so after applying this change and rebooting I haven't (so far) noticed any difference - I'll have a better idea in a few days, or even sooner once I finish fixing my test equipment (fun)).

I'm in the process of evaluating if this helps solve my own imprecise/floaty-mouse-pointer issue (for me, the problem is tempramental and varies day-by-day, and since this morning my computer has had a "good" days, so after applying this change and rebooting I haven't (so far) noticed any difference - I'll have a better idea in a few days, or even sooner once I finish fixing my test equipment (fun)).

Can you tell me what the default values are? And also give the setting to default to return the values.

Also, this guy in the video has this option in the power plan. How did he added this setting there?

This would be the CMD command to change the value to the Processor Performance Time Check Interval to 5000 milliseconds or 5 seconds (default 15 on high perf, 200 on balanced):

powercfg /setacvalueindex scheme_current 54533251-82be-4824-96c1-47b60b740d00 4d2b0152-7d5c-498b-88e2-34345392a2c5 5000

The benefit of this is that it will make your system check less how your CPU is working and generate a high amount of interrupts for nothing.

This helps a lot with interrupt behavior all over the system by a tone and some cores will find some rest which benefits your real-time application like gaming and your mouse movement.

You can even lower more when you check off certain options of the SSD's Coupled with good timer resolution change (people with new build windows 10+ you may want to do some research cause some stuff has changed on this) and disabling the dynamic tick [ bcdedit /set disabledynamictick ] and overall this is working pretty well.

And add up this to disable all USB power management from your entire device manager list with this PowerShell cmd:

Get-WmiObject MSPower_DeviceEnable -Namespace root\wmi | ForEach-Object { $_.enable = $false; $_.psbase.put(); }

Now from my experience, this is good enough to make a difference that I don't need to spend hours following those crazy optimization changes (network, device manager, nvidia profile, etc.), matter of fact it will even break the benefits you get from this.

Do you have any quantiative evidence that supports this claim? (i.e. actual benchmarks or profiler reports?) otherwise I'll chuck this into the placebo pile.

Remember, 15ms is still only 66Hz - whereas your computer currently processes over 10,000 interrupts every second. This is a drop in the ocean.

YEGODS DO NOT DO THIS you will lose data and possibly corrupt your filesystem. This option is intended for use on computers with HBAs that have those huge supercapacitors built onto them - you shouldn't do this with consumer-grade NVMe or SATA SSDs.

This is less harmful, but again, I really haven't seen any actual hard evidence that it does anything - except reducing the initial startup delay/warmup for some USB mice.

I didn't dive into much here but I did a before/after passmark run for the command in powershell if anyone finds it relevant..

Need reboot after apply setting or not?

Why do we have to do this while all pro players and streamers don't give a damn about a single thing like this? I highly doubt this is a fix to our problem. You can feel the floaty mouse even in BIOS or other operating systems, it doesn't matter.

becouse sometimes works ok,so must be something to be done,we keep going,i like to spend 1,2h after work gaming,and this shit problem bogles my mind!

Update,the problem is back,now no mather the number i change there its the same feling,its like whatever the thing is is adapting )))

Always nice to bump into a fellow sufferer... out of curiosity, can you tell me:

• Exactly what OS you have, including OS build number (e.g. Windows 10 22H2 is 19045)
• Exactly what CPU you have
• Exactly what motherboard you have, including the chipset name
• Exactly what SSD/storage you have, if it's an M.2 SSD, do you know what PCI-Express lanes it's using?

Thanks
