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’ve had great luck with Decky Framegen 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Meanwhile my Steam Deck refuses to enable even FSR 1 or 2 because all the guides are outdated due to the settings changing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 it natively, or use decky-framegen decky plugin to change DLSS to FSR3.
FSR4: use decky framegen to change DLSS to RDNA2 compatible FSR4.
FSR1: select it in the sidebar as the scaling method, set any game to a resolution smaller than 1280x800. It’s system wide.
As I said: it doesn’t work.
The options 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.
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.
I hope it’ll be officialy brought to Steam Os at one point.
Official support would require AMD dropping the RDNA 4 gpu core requirement from FSR4, it’s not something Valve can do anything about.
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😅
FSR1 is a simple frame upscaler, it’s used as one of the methods for resizing the image when you render something at s lower resolution and stretch it to full screen, along with bilinear and integer. Very few games actually use it directly.
FSR 2/3/4 are temporal (time based), they need to be implemented directly by the game engine but if they do have FSR2, (like Deep Rock Galactic), it works on the deck.
FSR3/4 officially needs an RDNA 3/4 based gpu, which the deck doesn’t have, but the plugin/mod converts DLSS calls in to a RDNA 2 compatible version of FSR3/4.
FSR3 without the frame generation part might also work on the deck natively, though I’m not sure if I’m misremembering.
