Hello, i switched to a new graphic card Amd RX 6700 XT and the game is unplayable, for what i read around the have problem on running old Directx 9 game ... so for now i can play using the integrated one thats work just fine.
I was just wondering if anyone have found a fix for this since the problem lies in the card not clocking high and give a massive stuttering even on 1440p ...

So after days of research i found 2 major problem whit this new amd card.

First you need to disable ULPS ( Ultra low power settings ) option from reg edit or whit msi afterburner cause the gpu otherwise will stay too low in frequency resulting in be unable to play

Second you need to restore the Shader Cache option removed from amd drivers long time ago, you can do that again whit regedit, found how to in a reddit discussion ( hope link is allowed )

This 2 fix allowed me to play the game but i still have some stutter whit the dedicated gpu ( Rx 6700 XT my case )
Using the Integrated graphic card its perfect no stutter even on 1440p.
Sadly im unable to do like i was doing whit my old Nvidia graphic card, to enable Antialiasing etc overrating game settings otherwise i have again stuttering and bad performace ...


Thats all i hope can help someone in the next future

People have mentioned turning on, or off, mouse trails re: stuttering with newer cards.

That might help?
