How to use optiscaler on Black Myth Wukong?

[JetCatt]

I'm trying for 2 days to use OptiScaler FSR 4 on Black Myth: Wukong and I've tried all kinds of things.

I installed OptiScaler directly from the GitHub page and also tried using GOverlay, but none of it worked. The spoofing seems to be working, but when I enable DLSS, OptiScaler doesn't recognize it and falls back instead.

In other games I've tested, it works perfectly fine.

I've tried Proton EM, Proton GE, and Experimental, and also used DLL override commands to force the correct libraries. ChatGPT helped me during these 2 days, but we couldn't find a solution. It seems like Unreal Engine behaves differently compared to other games.

Can someone help me?

The problem is the Compatibility mode (sth related to DirectX 11 and 12), but just don't start BMW with Compatibility mode on Steam and it should be ok
