Forced Upscaling is Personally Unplayable - Literally

[aiqa]

Then why is there blurring all over my demonstration video, where I show at the end that I have the game set to FSR at 100% resolution?

It's not easy to see the difference between video compression stuff and blur from the game. The bitrate isn't good enough for that. Youtube doesn't even allow that.

What antialiasing setting are you using? The TSCMAA + Jitter has a temporal component, so could cause blur in motion. But note that without temporal antialiasing, you can't fix the escessive shimmering in FF.

Where's that checkbox??

I meant the dynamic resolution checkbox (that checkbox enables upscaling in certain situations). And set the resolution slider to 100. When you do those 2 things, you completely disables any upscaling. So any remaining issues have nothing to do with upscaling.
