Oh wait what, I didn't actually hit submit on this, I went to work and forgot about it. Sorry, Anyway what I was gonna say was Temporal Upscaling, I don't think you already have it and it can be quite powerful when done correctly. Lets you render out a full image in 2-3 frames or so instead of 1, yet all 3 frames are still visually useable. Something like: https://www.shadertoy.com/view/3l3XR7. If done right you can get perfectly real-time results at full resolution but only render half or even a quarter of the target resolution. Some Minecraft Raytraced shader packs use it and it's hella powerful. Been meaning to implement it to my own shader pack.

Weird cause I also changed the title before I went to just refer to temporal upscaling since you already have the other idea I was gonna mention.

I do have upscaling, both TAAU and my own upscaler that uses some things from FSR 1.0(used to be heavily temporal but it smeared too much)
