Have you tried playing with FG? I am not fond of it but after playing with it turned on for a while I will begrudgingly say it will become a thing whether we like it or not. Tried in a few different games but played quite a few hours of Hogwarts with DLSS FG and I must say it works remarkably well. Yes, Hogwarts is relatively low-tempo making it a good use case and I do see the increased movement artifacts plus the transition artifacts but 1.5x-2x the frame rate and smoothness it brings is hard to argue.
Oh yeah, it'll become a thing I'm sure... Have played with it, don't like it, pretty sensitive to latency / differences in responsiveness, and that's not even considering artifacts. Also... its smoother... but Hogwarts doesn't remotely need it
Even combat is slow as molasses, built for gamepad and analog sticks. You say good use case... I see a game that now has artifacts added to what should be an immersive experience first and action game next. Whats the point?
There are many things 'a thing' these days that I strongly dislike. Such is life I guess
I'm not seeing much in the new 'generation' of gaming/gamers though that really benefits me OR makes us play better content. The crutches to maintain performance in games that really don't have much to show for it are just hilariously silly to me. Darwin will fix this in the end, hopefully. The bottom line is the vast majority of devs in big studios are brutally untalented these days, and it shows - in writing, dialogue, graphics vs performance, in soul/character of the games, everything. That vast majority is simply producing fast food, and the kitchen is ill equipped to ever push a real menu with wholesome items. FG fits right in, as does DLSS / FSR and RT. Just pour half a dozen abbrevation-sauces over your game and maybe marketing can make it look like something eh? Its disgusting and the results prove time and time again that its not really a nice way forward. Millions are poured into content that's forgotten tomorrow and buggy today.
And then occasionally a game like BG3 comes out that just runs native, flawlessly, with no crutches and looks the part, proving to everything else how deep down the rabbit hole of bullshit they went. There's a sharp drop in the quality of releases and it seems to coincide perfectly with these fake frame technologies.
