Starfield is Free to Add DLSS Says AMD, Partners Prioritizing FSR a Request Not a Demand
https://wccftech.com/starfield-free-to-add-dlss-says-amd-partners-prioritzing-fsr-a-request-not-demand/
"While AMD doesn’t demand that partners exclude DLSS from their games at launch, it seems they do politely request it. AMD pays publishers to bundle their games with their graphics cards (Starfield, Avatar, and more are launching with Ryzen and Radeon bundles) and asks them to put FSR first as part of the deal.
“Money absolutely exchanges hands. When we do bundles, we ask them -- ‘Are you willing to prioritize FSR?’ If they ask us for DLSS support, we always tell them yes.”
Okay, so there’s initially an option to still support DLSS, but once a publisher agrees to go FSR-exclusive, is that locked in? Again, it seems the answer is no, as Azor reiterates that “if and when Bethesda wants to put DLSS into [Starfield]” they’ll fully support it."
They certainly took long enough to come out with an answer. So it sounds like there is nothing specifically preventing developers from implementing DLSS but they do put an emphasis on having FSR support "first". It would explain why some games launch with FSR but add in DLSS months later.
Avatar: Frontiers of Pandora PC Trailer Stuns, Both FSR and DLSS Supported Despite AMD Deal

I'll likely skip cause I never really liked the Avatar franchise. My flavor has always been with the Air Benders
Oh god, Radeon is following Nvidias shitty numbering scheme with DLSS where you have DLSS 3 which was marketed as "Frame Generation" but then Nvidia later updated DLSS 2 to version 3 so now it's all sorts of dumbness. So now you have DLSS 3 Frame Generation, DLSS 3 Super Resolution and DLSS 3.5 which could or could not include Frame Generation depending on the GPU. Radeon could have at least done something different but guess not lol.
