I've used my 3090 with Nvidia super resolution just watching old shit I downloaded back in the LimeWire days that for some reason I was still holding on to and the result is not perfect but it is pretty decent.
For instance I had a copy of chobits that was probably in hell 240i resolution or something, and with Nvidia super resolution it looks only vaguely indistinguishable from the 720p stuff you can stream online.
Of course, when you use Nvidia super resolution with the 720p stuff it looks stellar, so higher resolution by default wins over AI up resolution but it works in a pinch
I've already dumped my esxi servers and am using proxmox and hyper-vm instead.
That's one less customer for them.
