Thanks for the response, I actually figured it out.
If I run GE-Proton9-27, Frame Gen works fine. If I use anything newer than GE-Proton9-27, I get the DLSS option, but only AMD FSR3 Frame Generation - It seems like a regression with recent Proton builds, as it also happens under Steam Proton 10.
I might try running a newer version of Proton when I get time and see if the launch option you’ve quoted resolves the issue, right now I’m just glad to have Frame Gen working again.



Repacked version here, runs faultlessly with very little effort on my behalf.
