Atomic Heart - Nukem9/dlssg-to-fsr3 GitHub Wiki

The game doesn't recognize the main loader (a 186KB file), and after enabling the DLSS G option, the game disables it again.

This issue was resolved by integrating the dlss-to-fsr3 mod into Optiscaler. Now the loader is included within it and functions more properly (you still need dlssg_to_fsr3_amd_is_better.dll file).

To enable dlss-to-fsr3 in the game, you need to install Optiscaler 0.7.7 and activate the DLSS-G mode in Optiscaler or via the optiscaler.ini file:

[FrameGen]

FGType = nukems

After this, you can enable frame generation in the game's settings.
