Why no zoom? what is the point of video, it will have artifacts of video compression. I can instantly see it as you move. I use 1440p because i cant see the difference between 1440p and 4k.
Start 45 fps 4k default ray tracing on up to the stairs
1:10 65 fps 4k fsr default ray tracing on up to the stairs
3:10 default 1440p at epic settings Ray tracing on. 85 fps up to the stairs.
3:55 1440p FSR Ultra Quality epic settings with Ray Tracing on. 111fps up to the stairs down.
6:20 default 1080p at epic settings Ray Tracing on. 115fps up to the stairs.
I cant find 1440p screenshot but these are 4k its night and day comparison. The whole screen in 4k FSR UQ looks blurry in comparison to native.
