FSR1: select it in the sidebar as the scaling method, set any game to a resolution smaller than 1280x800. It's system wide.

FSR2: find a game that supports it natively.

FSR3: find a game that supports it natively, or use decky-framegen decky plugin to change DLSS to FSR3.

FSR4: use decky framegen to change DLSS to RDNA2 compatible FSR4.

As I said: it doesn't work.

The option isn't even in the sidebar menu anymore

And downvote me all you want, but it doesn't change the fact that my Deck isn't letting me turn on FSR

Apparently they renamed it to "sharp" at some point, probably because "fsr" doesnt mean anything to people who don't know exactly what it does.

First set scaling mode to "integer", and change the resolution of the game under 1280x800. If the image shrinks, the game is actually changing the window resolution and not just render resolution. If not, try changing between windowed/fullscreen.
Then change it to auto/fit/stretch/fill, and change "Scaling filter" to sharp, and you have FSR1.

According to gamescope, FSR still isn't turning on
