Sadly I doubt the old consoles are getting any more titles, it's not just technical hurdles and the fact that FSR2 wouldn't run that well on Xbox One/PS4 anyway. But that by the end of the year new gen will have an install base of like 50 million and developers just don't want to deal with supporting two and a half console generations alongside PC. It's why Gotham Knights just dropped previous gen consoles certainly.If this works like the review purports, it's a win for everyone. Developers can target one implementation, tons of nvidia cards are supported and obviously AMD gets a big feather in their cap for showing that they could pull it off and for having "feature parity" with DLSS, which so many outlets absolutely obsess over. Gamers can tick a box and most won't be able to tell the difference in IQ most of the time but they'll notice framerates up over 60FPS.
Also, guaranteed support on a huge breadth of titles because of the way it can help extend the console lifecycle and let more developers release "60 FPS/4K/RT" games.
Still, it'll be cool for any remaining devs not using UE5
