nvidia 3070 to amd 7800xt: bad performance

[tAz-07 0]

Hello

 

I have move from a Nvidia RTX 3070 to AMD 7800XT. This new card is very good except for Arma 3...

 

I have used DDU to cleanup my PC prior the change and allready try the auto detect method, change every settings and play with adrenalyn software....

 

When I look at Hwinfo and try to compare difference between nvidia & amd I dont see any change regarding CPU and GPU usage is even less due to better performance I guess...

 

I have no idea where is the issue here and begin to think it is due to old Arma  3 engine...

 

thanks for any help / hints

 

edit: looks like more an issue with amd and dx11...dxvk at least allow me to play the game again
