It’s currently possible to force games to use FSR4 through decky plugins/launch options. However it looks like Valve is planning to add official SteamOS support for using FSR4.

      For a while, AMD had been kind of… non commital about this… I think they just genuienly did not know if it would be a software/hardware engineering problem they could actually solve,.so they would not want to promise something they didn’t know if they could deliver.

      In that time period, a whole bunch of random opensource people were basically trying their damndest to reverse engineer a seemingly accidentally leaked version of an AMD driver that at least made some of this maybe technically possible.

      By the time the OS reverse engineers managed to basically build an unofficial driver that did actuslly work, though maybe not with the greatest performance… well, I’d guess AMD basically copied some of their homework, and then did their own thing.
