I’ve tried a number of games both from my Steam Library and other launchers and none of them support HDR in the games settings. Have I missed something or do developers need to update their games individually one by one to support the HDR on the new Steam Deck OLED? Maybe someone has a list of currently supported game titles from Steam?
Good question!
If you go to Steam Store > Categories > Great on Deck > Visuals & Viewpoint > HDR Supported, you get a list of 8 games (scroll down) that doesn’t include lots of obvious ones like Horizon Zero Dawn, so that’s useless.
Someone in another thread linked this list, which isn’t Steam Deck specific, but if you look to the ones showing support for Linux (Tux penguin icon) then it’s probably a start anyway.
