Only 2 cores being fully utilised.

I have a i5 9600k with 16GB 3000MHZ ram and a rtx 3070 with a 750W psu for context. Whenever i do anything mildly cpu intensive, the frame rates drop to below 5 or even 0. Task manager says cpu is around 60%. Resource monitor says core 0 and 1 are both pinned at 100% while other 4 cores at around 40%. I know its not the GPU bottlenecking it as  had the same issue with my rtx 2060 before i upgraded. I have reinstalled windows without losing my personal files but i say no change.

What game?

Not every game is built to be multithreaded and utilize all cores. It's common for some games to be all one thread, or one main thread + one render thread. New fancy games on modern engines with Job Systems can go wide across cores better. DOOM Eternal as an example, is entirely "job-ified" and apparently has no dedicated main thread for the game loop, so it might be a good game to see how well your CPU performs with parallelization.

This happens in every game from cod to beatsaber to pavlov. Only started a month or 2 ago

it used to be fine but now all games fps are dropping and before, this never happened.

fully reset windows with all files deleted, most games now work but beatsaber still doesn't
