A 4090 at 4K maxed settings with DLSS Quality should get 60, Based on their sheet.
It's an AMD sponsored game though so that means the RT quality will be the lowest possible just to tick a marketing checkbox just like Far Cry 6 and Resident Evil Village.
Yeah it's a shame amd somehow managed to swoop in and get partnership with this as originally it was nvidia involved and the game was going to be ray tracing only like metro ee. AMD doing what they do best, holding back next gen visuals
