Implement Xess 2.1 or newer to the engine

[MatiReviews]

Hi! I want to say I'm not a developer so I don't know how hard this can be to implement.

I've read that FSR 3 was coded different so that's why is not implemented yet.

But what about Xess 2.1?

The newer version supports Frame Gen and Low Latency mode for non Intel Cards. I think that's a win for everyone.
Also from what I've seen on YouTube and also tested myself, Xess 2.1 has a better upscaling quality than FSR 3.1.

Would it be possible to have an implementation of this feature?
I know Intel provides an official plugin for Unity and Unreal. But nothing for Godot.

Thank you!

• Related to Add support for AMD FSR 3 frame generation (currently, FSR 2.2 is supported) #8768.

XeSS is under a proprietary license and is only distributed in compiled form for Windows, so it's not possible for us to integrate it directly as a core feature unless it became open source. (The repository doesn't contain source code.)

However, as per intel/xess#38, it's still possible to have XeSS support in Godot if a third party develops a plugin (or engine fork) for it.

In contrast, it would be technically possible to port FSR 3.1 to Godot by doing a similar approach to what was done with FSR 2.2.1, but it'll be significantly more involved this time given AMD has changed the FidelityFX repository structure with FSR 3.0.

Thank you so much for the response. So there's a possibility in the future, whether is Intel's or a Third Party.
