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.
Interesting, I wonder if this is more stable than it is on Windows?
I find it handles controllers just fine, but I find the headset (the official Xbox one) drops out regularly. Still leaps and bounds better than Windows Bluetooth, but the drops definitely worsen the experience. Although it also did that to me on Series X.
