I understand you deliberately wants to deny these features are awesome, because you can't use them. Once again, it's like seeing a 1080p SDR TV owner claiming that 4K HDR OLED is just a gimmick.
Hours of tweaking?
Literally takes seconds.
AMD has no AA solution that comes close to DLAA.
AMD has no upscaling that comes close to DLSS.
AMD has no downsampling that comes close to DLDSR.
Facts for you. And every single person with proper RTX experience knows this is true. Or you can read the 1000's of tests that confirm it.
Techspot compared DLSS2 with FSR2 and FSR2 did not win in a single game. DLSS2 easily won in pretty much every one of them, about 26 different titles.
AMD don't even have a feature to counter DLAA or DLDSR, or DLSS 3 or 3.5 for that matter. Reflex, yeah no. You pay less to get less. If AMD was just as good or better, they would have higher marketshare.
When you had DLSS, DLDSR and DLAA for years, you simply don't accept what AMD is offering, even if you can save 100 bucks on average. Simply not worth it when resell value is lower for AMD hardware anyway (less demand and AMD lowers prices alot over a generation)
