Adding AMD FSR 2.2?

Post by Daryn »

With AMD releasing FSR 2.2, I'm wondering if it'd be possible to implement into GZDoom?

https://github.com/GPUOpen-Effects/FidelityFX-FSR2

If anyone's interested in looking at it. I'm not going to call this a full feature request, as I'm not entirely sure there would be a benefit to VRAM usage. In my mind, there should be, but I don't know enough to really make that claim.

Check it out, though. At the very least it's an interesting repo to browse.

This is way out of scope for a Doom port.

While this is cool tech, I have a feeling it would struggle with our use cases as it relies on coherency between frames, for example a monster making a 45 degree turn is probably too much for it.

If it was easy to implement, I'd say give it a try and find out, but it looks like implementing this into GZDoom wouldn't be as straightforward as it is for a modern engine. I just figured I'd bring it to your attention.

It's not that easy to implement because GZDoom does not save data between frames which is important for an implementation like this. Plus it also needs a lot of other data in order to function (such as vertex shader info) which is not readily available.
