It’s not compatibility man… it’s simply Nvidia is Slacking off it’s either a driver or RTX 5xxx hardware issue. i assure you RTX 4xxx cards are doing just fine with DLSS it’s just the RTX 5xxx that fail in this regard… and as I’ve said D2R is not the only game DLSS fails for RTX 5xxx…
this is a much broader issue that Nvidia has to solve…
