Ok, I was able to enable FSR 3.1 without any issues, including Frame Generation.
It’s super simple:
- download OptiScaler HERE
- download Fakenvapi HERE
- open the folder with FligthSimulator.exe
- rename nvngx_dlss.dll to nvngx.dll
- edit nvngx.ini file and modify OverrideNvapiDLL=true (from auto)
- Rename OptiScaler’s nvngx.dll to dxgi.dll
- copy the 4 files you see in the screenshot from OpiScaler folder to FS folder
- run EnableSignatureOverride.reg from OptiScaler folder
- activate frame generation in AMD drivers panel
- start fs2024 and choose DLSS + DLAA
- you can’t click frame generation under DLAA. To start frame generation press INS on keyboard. Select 3.x from the first dropdownlist and click APPLY.
You win
