Windows 10: Ive upgraded to windows 11 a week ago, my games are running terrible, stutter fps drop etc.

After my upgrade to windows 11, ive noticed that my cpu usage on any game is running max 10-15%, causing my game to stutter, or fps drops in cpu demanding games like valorant, which ive never had before.My Specs:i5 8400rtx 306016gb ram256gb ssd2tb hddEven with the upgrade as well my task manager is bugged giving wrong info about cpu and gpu usage, where it says my gpu is 100% usage on ide, and cpu usage 50%, while programs like nzxt cam, and rivatuner show the different infoMICROSOFT FIX THIS PLEASE

Sudden FPS drop/Stutter

Since 2 days ago, I just turned on my Computer, and it starting having issues while I was playing Witcher 3 (starts with decent fpsm and then very low fps, dropping to 35, then 20, and stopping at 12 or so, in a matter of seconds, in a matter of 1min of starting the game), also stuttering without any high demanding programs, randomly. I was playing at 45-60 fps, without any stutters or sudden fps drop. Have tried other games the issue persists. Even setup everything to low settings.
I have ran several tests with several tools, all seems normal, no sudden memory spikes, or temperature raising out of the ordinary, nothing that would indicate such an fps drop or stuttering.

MSI Afterburner

I also did the reset option on Windows10, completly cleaned out all my personal info from the windows partition.
So at this point, I am not sure if it is a software issue or a hardware issue.
Any suggestions are greatly appreciated.

Edit: I kept doing some tests to find out the issue. And this happened before and I was able to replicate it. Same thing happened as before, till I set it up to fullscreen, Alt+Tab from the game and then back to the game, FPS went up to 50 again, stable and good, dropped after a couple of seconds. After a bit it went to 2-5 fps, and I had to shutdown the game, because even the sound was getting messed up.

In this image those ups and downs in the GPU usage are when the fps dropped really hard and the sound got messed up.

 

Gaming FPS Drop/Stutter after recent Windows 10 update.

After this new years update, I noticed that my games have been getting frame drops and stuttering. I have a NVIDIA GEforce 1070 and I was able to run games such as CS:GO or League of Legends smoothly before the new year. However, after the recent Windows
10 update, my computer can't handle the games well. For example, League of Legends ran at 144 fps (I capped it there) and constantly ran at 144 fps before the new year. However, after the new year update, my League fails to consistently run 144 fps, drops
down to even 90 sometimes, and there is a lot of frame stuttering that is inhibiting my ability to play the game. Is there anything I can do to fix this?

 

games drops fps and distorts audio ( windows 11 )

hi recently ive went through a problem inwhich games drop fps to around 1 and audio distorts , this is just the diplay fps since the game says the fps is normal ( through nvidia performance window ) the bug affects other apps too and goes away when i turn off the game ,the issue isnt a driver issue since ive clean installed the drivers using ddu , ive tried restarting my pc ( with keep files ) and it still happens , not all games cuz the bug but most of them

here is a list of the games the cause the bug :
trove
halo infinte
fortnite
pc building simulator
and geometry dash ( but rarely , it usually happens in geometry dash when i use another app for a long time while the game is running in the background )

the only game i play that doesnt cause the bug is minecraft bedrock ( havent tried java )
