3080ti performance issues all of a sudden!

[cheesewizard007]

Hi All, so i had an issue a few weeks ago where out of no were my pc wouldn't power on and if it did it would only do so for a few seconds at most, i have had issues with no power etc. on older builds in the past so followed all the usual steps (basically tore the thing apart and systematically rebuilt it several time haha) nothing worked so figured it was the motherboard. then out of the blue its working again, ran a few stress tests and every thing has been fine?? so took the W!

But, performance in game is absolute garbage to what it was before, i used to get 100fps on high settings in Rust and it looked great! now it is un playable and i get between 45 and 50fps going to as low as 24 and and it is doing similar in Satisfactory with terrain and models not rendering very well at a distance if at all and overall games are looking terrible. i have updated and reinstalled drivers , updated bios, reset Nvidia settings etc. not sure what is going on so thought id ask about and see if anyone has had a similar issue or advice?

 

I am running:

Ryzen 9 3900X

32gig of DDR4 @3200

ROG Strix X570-E MoBo

Aorus Xtreme 3080ti
