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.

Why Valve is awesome!
I’m also very surprised this is possible. I know others like Digital Foundry have replaced DLLs in games under Windows, to change the upscaler or upgrade it. So having this in Steam builtin doesn’t come as a surprise to me at all. What surprises me is, that the Steam Deck seemingly is able to handle FSR4? I thought AMD is working on making FSR4 work on RDNA 3.5 and later 3. But Steam Deck has RDNA 2 hardware. Maybe I don’t understand what I’m even talking about, so please correct and explain this to me then.

If I recall correctly, they specifically said that FSR 4 would be coming to RDNA 2 systems early next year.

Oh wow, you are right, I totally forgot about that.

Might be for other hardware, like self built PCs and Steam Machine, with Deck gaining support later than.
