FPS drop in games

windows updates are causing fps drops down to 20 - 10 fps in games that used to run at 80 -100 fps. I have tried every single fix out there. i've tried several different graphics driver versions, reinstalling windows, even a complete factory reset . specs - Lenovo legion 5 pro - RTX 3060 laptop gpu, AMD RYZEN 5800h, 16 gb Ram, 1 tb ssd

 

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.

 

Huge fps drop on games after upgrading to Windows 10.


I recently upgraded to Windows 10 because there are a handful of upcoming games that I am interested in that are only available from the Windows store (Gears of War, Killer Instinct, and Quantum Break), and I also want to take advantage of dx12 when games start to utilize it. I've read that some people have noticed a minor dip in fps after upgrading, but my experience was so bad I had no choice but to revert back to Windows 7 Ultimate.

Examples:

Rise of the Tomb Raider- Windows 7-max fps-62, min fps-43. Windows 10-max fps-44, min fps-31
Just Cause 3 Windows 7-max fps-54, min fps-30. Windows 10-a consistent 30 fps.
Project Cars Windows 7-max fps-118, min fps-88. Windows 10- max fps 88, min fps-73.
Mad Max Windows 7-max fps-111, min fps-88. Windows 10- a consistent 60 fps.

As you can see, these represent more than just a "slight drop" in framerate which I was willing to accept. Is anyone else having similiar issues with their gaming rig?
