I built my new pc a couple weeks ago and I have been running into an unusual problem and i just can't fix it. I need help.
When i launch cs go after i just restarted the pc it runs smotthly at 200+ fps, however 20 seconds or so after i join a match the game gets really choppy and slow with 20-40 fps max. The thing is that if isnt thermal throttling because ive been looking at the temps, but the cpu and gpu run at 2 - 20% at all times. The cpu and gpu are running at 30 -50 C at all times, never getting higher. I have a similar issue on League; it runs at 20-40 fps but my graphics card is running at 2% usage and cpu at like 20%.
I have tried everything, I have reinstalled windows (although with the custom installation in which it doesn't delete your files).
I know the gpu and cpu are not foulty, cause when i run fur mark and cpu burner ther do work and they use 100% performance on task manager.
Intel core i9900K
Meg z390 Ace
32 gigs of ddr4
EVGA RTX 2080 Super
WD 1tb nvme
Edit 1: There are some games that do run good and use 100% of gpu, for example Battlefield 1 runs at 70 ish fps on ultra at 2560 x 1440.
Edit 2: Welp I tried everything but it didnt work so i nuked my os and did a clean install. It's working good now! Thanks everybody for the help and I hope you have a nice week!!
