Am I wrong in thinking MS has some sort of preferential deal with AMD for PC versions? And maybe Sony too? I feel like most of the console first party title ports tend to be AMD sponsored, and very light on any extra features on PC.
Pity though, I bet this game could've really used DLSS3. Maybe it's still possible to mod it in? I think if they implement FSR2 well enough it's not really a big deal not having DLSS, but having frame gen would be nice. It did seem pretty dubious to me back when they first supposedly showed FSR3, and given that they've stayed dead silent ever since it seems like their frame gen feature might not even see the light of day this generation.
RT would be a nice addition too, but if they had it in any form for the PC port, I think they'd have mentioned it, so I have to assume there's no RT at all. Usually AMD at least pretends to have meaningful RT features, even if they're of marginal benefit due to their limited implementation. But I guess that's just how the dice rolls sometimes. Expecting Nvidia exclusive features to be implemented in every game is just not going to happen, and people should keep that in mind when thinking how Nvidia's cards might look IF a game supports them vs. just raw performance without tricks that require game specific implementation.
