So,

I have this problem for a long time now and cant figure it out.

Whenever i play unreal engine games at more than 60 fps (and some other games like gta and war thunder) my screens randomly freeze for 3-5 seconds, blackscreen and then the games crash (only war thunder doesnt). 
I have watched HWmonitor but didnt notice anything suspicious, my drivers are up to date, the temps are at ~60°C max, and the only info i ever got was war thunder telling me that my graphics card driver hung. 

Now im confused though. Reinstalling the drivers doesnt work, the only thing that sometimes work or at least decrease the chance of this all happening is by lowering the graphics/load on the card and cpu.

My specs are:
- 3080 ftw3 ultra gaming (obviously)
- i5-9600k
- 16GB, 3200 GSkill Aegis
- 750W gold PSU

Im so confused on whats happening or what could fix it
