I’m no patent lawyer, but every graphic in that patent describes a 540p image being upscaled to a 1080p image. No mentions of a 2160p image, although I didn’t read the full text.
I suspect this feature is more intended to allow games like The Witcher 3 or Wolfenstein that output a really low resolution to present a better image.
Although, having tinkered with FSR3, I’m generally not impressed with AI upscaling at low source resolutions. I’ve heard DLSS does better in those conditions, but even at 1080p->4k there’s noticeable artifacts and temporal instability. I much prefer it at 1440p->4k. So I’m somewhat unsure how much I’d even want 1080p->4k, although I’d certainly try it and see, and I kinda think I don’t want 540p->1080p.
When you start getting up to/past 1080p, better texture quality >> higher resolution. I’d rather they spend the extra GPU cycles to take their 540p content from “Low” to “Medium” quality before upscaling than take it from upscaling 1080p to 2160p.
I’ll believe it when I see it, but that’s cool if true!
