A month ago i purchased a Sapphire Nitro RX 7900 XTX, the card has an amazing performance, but i noticed a little bit of stutter in some games and WRC generations crashed sometimes

After testing some settings, finally i don't have any performance issues, this is what i did:

1.-Format your PC to install a clean copy of windows, i'm using windows 11 pro
2.-Update all drivers and windows too (i have the latest adrenalin driver 23.2.2)
3.-In AMD Adrenalin, i'm using the preset "Balanced", you can change it in performance->tuning and gpu tuning control, seems like it works fine with the default setting, i did try the rage preset but the card becomes too noisy.
4.-For some reason, showing the Metrics Overlay of AMD adrenalin causes the stutter in some games (and it was the cause of the crashes in WRC generations), if you want to see your thermals and other info while playing, use another software.

These are the games i tested without upscaling (i have a 1440p monitor, but i'm playing with higher res using Virtual Super Resolution, you can enable it on AMD Adrenalin, settings->display)
