From everything I'm hearing I don't think there will be any doubt come the next gen of cards. Nvidia are in for a lot stiffer competition from AMD and Intel taking them on at the lower end.
AMD have to, FSR at its worst is not going to look anything like as good as DLSS 2.0 at its best, all we have is 4 minutes of a Youtube video showing FSR before launch, already Youtubers are lining up to say "at best its only as good as DLSS 1" which was ###### shockingly bad and they know it.
FSR WILL gain A LOT of traction with game developers, but a lot of the people reviewing and buying GPU's will poo poo on it, they are already setting that stage, its not even out yet, eventually FSR will become THIE standard but it will not help AMD's sales.
AMD have to be brutally aggressive, they have to have native reforestation performance that's better than Nvidia's DLSS performance, AMD have to make sure those looking for fault have nothing.
Only then will AMD gain ground on Nvidia.
