FSR4 has been great for me. Performance seems slightly worse than FSR3 but the increase in visual quality is well worth it, particularly because IMO FSR4 on balanced both looks and performs better than FSR3 on quality.
I still avoid it when I can because native rendering will always look best, but this is definitely really nice for steam deck where the hardware is much more limited.
I’m tempted by all these frane gen mods, but I don’t want to install decky loader for now as Steam Os already feels a bit too beta for me compared to want I’m used to on Gnome or Playstation.
Official support would require AMD dropping the RDNA 4 gpu core requirement from FSR4.
Even if it did happen, there would be quite a small overlap between games that have FSR4 and ones that are able to run on the Deck well enough in the first place.
Well I’ve just learned that you already had FSR 1-2 in Steam OS without adding any plugin. So I guess what I was talking about is already there but I’m just not using it😅

I’ve had great luck with Decky Frame Gen so far. Just finished a Resident Evil 7 and 8 playthrough with a rock solid 60 FPS. The only thing I really noticed is occasional audio sync issues during cutscenes. Very pleased!

Meanwhile my Steam Deck refuses to enable even FSR 1 or 2 because all the guides are outdated due to the settings changing

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 them natively, or use decky-framegen decky plugin to change DLSS to FSR3.
FSR4: use decky framegen to change DLSS to FSR4.
