    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.
