How I fixed my performance problems!!!

I've been playing since launch.

Alienware R12
Geforce RTX 3080
Intel i7(11th gen) (water cooled)
Very fast ram
Very fast SSD.

I CRASHED EVERY 30 minutes!!! and then I'd load back up and crash again every 5 minutes after that.

I tuned all the performance options in the NVIDIA Control Panel.
used DDU to flush all NVIDIA Drivers and start from scratch!

performance was ok for about 30 minutes again and then CRASH!!

This time though, black screen and PC Reboots.

TURNS OUT my CPU Liquid cooling system was failing and the CPU Was throttling itself.

Replaced it with an old one from my Alienware R9, and with the new performance settings Holy beautifull!!! Running at 120 FPS no stutter just wow!!!

LESSON OF THE DAY!!!
check ur CPU Temperatures, and also the speed, you'll see it throttling down if that's the case!

CHEERS EXALTS!!
