From GE’s 7-25 release:
Usage remains the same:
WINE_FULLSCREEN_FSR=1 WINE_FULLSCREEN_FSR_MODE=ultra %command%
Modes available:
ultra - ultra quality
quality - quality
balanced - balanced
performance - performance
For reference, here is the formula used by FSR in case you want to make your own modes for different aspect ratios:
Ultra Quality — 1.3x scaling
Quality — 1.5x scaling
Balanced — 1.7x scaling
Performance — 2x scaling
You can still alternatively use a custom mode as well:
WINE_FULLSCREEN_FSR=1 WINE_FULLSCREEN_FSR_CUSTOM_MODE=3938x1108 %command%
As noted -- you must set the in-game resolution to either the ultra resolution added or the custom mode you provide, and set fullscreen mode.
The game will then up-scale that resolution to your screen's real size.
Try adding the mode command (WINE_FULLSCREEN_FSR_MODE=ultra - or any other mode ofc) as well. Perhaps then it will work.
Anyway, a lot of people are complaining regarding FSR issues with his latest releases.
