One of my non-Steam games (Ihanashi no Majo) runs perfectly in Desktop mode on the OLED using basically any Proton version.
When I switch to Game mode, however, it’s being forced into a messed-up HDR mode that results in the game being hideously over-saturated. I can’t even tweak the color balance manually, since that slider only applies to SDR.
Is there some sort of launch command option that would enable me to just start the game without HDR?
OK, so no matter what you do on certain games like Detroit become human (which mandatorily use HDRbtw) it’s usable abd it’s gonna look like crap so I found a fix. you go ahead and push the steam key go to settings go down to display, scroll all the way down to HDR visualization And you’re gonna click “none”. That is it. no more garbage on the screen that screws up the experience.
