Foul play? Noi smoking gun? It's been confirmed by John that 3 devs on seperate game(s) have stated they had to "remove" dlss due to sponsorship, I can't see him making that up, he's not MLID material..... And as said, the whole thing and that image speaks a thousand words, again, gamer nexus summed it up perfectly (and they ain't exactly nvidia bias given their very controversial content that got them black listed by nvidia and they called them out for this)
Why not implement all 3, let the customers choose what works best based on their setup?
FSR is nowhere near as good as dlss, people say this all the time and sorry but it just ain't so (not just based on my testing but hubs, tpu, df, oc3d, gamer nexus etc.), especially at resolutions lower than 4k and if using any of the lower presets (and this is becoming more necessary now and will only be more common going forward on older gpus), again, it just smacks of amds "we know what is best for you, it's our way or the highway"
In terms of speed and covering user base, fsr and dlss is extremely easy and quick to implement, more so if the game already has a TAA based AA in it (which 99% of games do now), even according to amds very own guide, if a game has dlss, it's even quicker for devs to implement fsr:
This is not some huge piece of work that needs a proposal and to go through multiple meetings/stages to get planned for, a junior/intern could easily do it (especially since dlss doesn't require as much fine tuning per game to get good results like fsr does)
