Oh boy, seems like Nvidia just one up AMD again by porting FSR code (or very similar) into their new Sharpen+ filter in the 471.11 driver (only via Geforce Experience overlay, NVCP does not have this option yet).
The result is quite mindblowing, here is an example of CP2077 4K Native vs 4K DLSS Performance with Sharpen+

This make the 4K DLSS Performance look 99% like 4K Native, people would be hard pressed the tell these 2 apart in a blind test.
I have also tried 1080p and DLSS Quality with Sharpen+ look remarkably better than Native due to DLSS having better quality AA, kinda insane really.
Note that you can only take screenshots with Sharpen+ applied with Shift+Print Screen, I was scratching my head off when Afterburner doesn't take screenshots with Sharpen+ applied.
