DLSSTweaks (Force DLAA) not working with Observer System Redux (Unreal Engine 4)

[door665]

Installed DLSSTweaks through the executable config, it suggested using winmm.dll which I accepted.

Binary Path: SteamLibrary\steamapps\common\Observer System Redux\Tokio\Binaries\Win64

Enabled Nvidia Sig Override. Manually replaced the latest DLSS in the plugins folder, version was 2.4 I think, with the latest 310.2.

The game works perfectly without DLSSTweaks with the regular Quality profile, defaults to preset K. Great!

All I did then was to just Force DLAA and I get a fatal error after the initial screen splashes.
