Upscaling and Frame Generation are disasters meant to conceal unfulfilled promises from GPU makers for 4k gaming, and as a coverup for the otherwise horrible performance some modern games have, even at 1080/1440p resolutions.
Upscaling will never, no matter how much AI and overhead you throw at it, create an image that is as good as the same scene rendered at native res.
Frame Generation is a joke, and I am absolutely gobsmacked that people even take it seriously. It is nothing but extra AI frames shoved into your gameplay, worsening latency, response times, and image quality, all so you can artificially inflate a number. 30FPS gaming is, and will always be, infinitely better as an experience, than AI frame doubling a 30fps experience to 60FPS.
and because both these technologies exist, game devs are pushing out less optimized to completely unoptomized games that run like absolute dogshit, requiring you to use upscaling and shit even at 1080p just to get reasonable frame rates on GPUs that should run it just fine if it was optimized better (and we know its optimization, because some of these games do end up getting that optimization pass long after launch, and wouldnt you know… 9fps suddenly became 60fps)
Or i just check pcgw and get disappointed. Oh well, if I can at least change the frame weight it’s usually bearable, otherwise I’ll just not bother
edit: or if the game lets me hack it off, otherwise I’d rather skip
edit2: also you can use FSR on pretty much any game now, regardless of AA, at least that’s what it looks like from my driver. So forced upscaling usually equals forced taa
You can run FSR natively on many games now, but they don’t all support it in the same way, nor the same version, and it also varies by your hardware.
You can also hack FSR of various versions into various games via … well, the FrameGen addon on Decky, for the Steam deck, is really a collection of a whole bunch of other hacks/mods/implementations for other games, and you can run a lot of those independently on linux or windows … but there are a lot of variables when you get this specific.
