You’re using FSR through Gamescope, which is configured entirely by the Steam Deck’s version of the Steam client. This is FSR for anyone using any steam client (or using Heroic or Lutris!) and can be enabled/configured via some environment variables.
For those of us using X11 instead of Wayland this is one of the simplest options.
For Steam Deck users it doesn’t really matter because you get it thru gamescope/the Steam Deck UI.
I’m on proton 8.6 and I can use FSR on steam deck, what i’m missing here?
