Have you tried using the 21.2.1 drivers? I use those and get great FPS performance on my 6900 XT.
Also, the cause of your low FPS is GPU utilization. It doesn't get fully used and so you have a loss in FPS. I made a thread about this as well.
yes. have testet both drivers. on both directx11 doesnt get more than 40-50fps.
i konw that is not fully utilized. but dont know why. and why only in directx11.
yes. the 3d mark scores are nearly the same. them on the photo above was with 21.3.2 uninstall it with ddu and test 21.3.1 , same expirience. i wait for the amd support (made a ticket) when they cant help me, i will go back to my old card.
Same problem, still no clue what is going on, have tryed all you said, after a while the same resoults, CPU 2 is going 100 %, and only CPU core 2.
Too bad you can't try another motherboard. I think it would be educational, say if you had an am3 or am4 platform lying around. If the issue vanished than you know the issue is in the EVGA firmware or MB. Just a suggestion.
