FPS randomly dropping for a while then back to normal

[PRATZiLLA]

I've been encountering a weird thing while gaming which never happened before. I installed doom and the game will play fine for a few minutes at a stable 90-110 fps and suddenly drop to 24-30 fps for about 30-40 seconds (even in areas where I normally get excellent FPS) and then back to normal. I've tried Vulkan and OpenGL and all the V-Sync options but it's the same. Moreover, this is also present in Assassin's Creed Origins although it is much less often. 

 

I play on a laptop and it has been thermal throttling quite a bit with my CPU going over 95°C and GPU peaks at 90°C. I did try undervolting and disabling turbo boost but the issue persists and I don't think it is due to the temps but rather something with the game because once the bug is over the games go back to smooth fps over 60 at all times even if the CPU is throttling. Any solutions?

Random idea:

Was some other app maybe running and eating cycles for these periods?

Nope. I made sure to stop any unnecessary apps and disabled windows defender as well.

That was before the fact though.  What about during?  Programs can launch programs
