Help with Graphic settings with my RTX4080 in MSFS

[bloxboy 15]

Hi All, I recently purchased a new system which includes an Intel I7 and a RTX 4080. When in the graphic settings in MSFS, the "DLSS Frame Generation" option in not enabled. The text to the right when you put the curser on the option says:- " Change windows setting in "Display>Graphics and change default graphics to "Hardware-Accelerated GPU Scheduling", which I have and restarted the pc, but still the option is still not enabled. Any help would be greatly appreciated. Thanks for looking. John.

Are you on dx12? FG working only on dx12.

Frame Generation only works in DX12. MSFS defaults to DX11. So enable the DX12 (beta) option. Then you must completely close down and reboot the sim for the DX change to take effect. You should then be able to use Frame Generation.

I own a RTX4080 and this option was disabled and greyedout from a Win10 & MSFS DX12 fresh installation.

What Id did is to check if in UEFI the "Resizable BAR" option is enabled.

Then in Windows check the "Hardware-Accelerated GPU Scheduling", restart operating system if any change is made.

When back to MSFS make sure you changed from DX11 to DX12.

If the option is still greyed out,(like was in my case after doing all this checks), you need to enable it in the settings file:

Look for the file "UserCfg.opt" in my case (MSFS Store verison) was located at:

C:\Users\usrename\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache

Do a backup before changing any content. Then open UserCfg.opt with Notepad and edit:

DLSSG 1

Close and save. Start MSFS.

When back to the options menu, the option may appear greyed out but set to YES.

I don't understand why I can' turn it ON OFF from the menu itself...

Hope it helps!
