> In Cyberpunk 2077, running at 4K, it’s a surprisingly stable 60fps, albeit with the caveat of that using FSR 3 upscaling on Performance mode with Medium quality settings

So it's not running at 4K nor 60fps. I wish people would stop calling 1080p upscale through some dogshit filter as "4K"...

Not even an RTX5090 can run Cyberpunk at a consistent 4K/60fps without upscaling or frame generation, so it's not a realistic bar.

The AI-upscaled image is technically 4K though, looks pretty sharp with FSR/DLSS, and also significantly better than 1080p or even QHD.

I would call it TV 4k, not monitor 4k. FSR looks just fine from across the room.

I agree 100%. However, the upscaling is pretty good. You can tell it's not 4K, but it's also considerably better than simple bilinear resampling from 1080p.
