You can use it with Genshin by disabling fullscreen optimizations in the exe file properties, starting the game with a shortcut with “-window-mode exclusive” as a launch option in the target file, and disabling vsync. Although, playing the game with AFMF lowers my screen contrast so much for some reason that it makes it unplayable. The first time I did it, it didn’t have that problem. It also doesn’t happen with the other games I have.
