I'm reposting my old comment regarding DLSS frame-gen

If it can help me maintain a more stable FPS that would be a boon. If I'm playing a game with unstable frame rates with a lot of stuttering I usually get a headache after one hour. So if frame gen can help my PC run games at a more stable frame rate, then I'm all for it. The first gen implementation of it may be shitty. But after a couple of generations it can be good.

Look at where DLSS is now, DLSS is objectively shit but since DLSS 2 in some cases it can improve image quality. I game on a 1080p 380hz screen, and when I'm playing games with upscaling like DLSS or FSR, I'll run the game at 4k and then run the upscaler on performance mode which is basically rendering the game at 1080p. The results are much better than just running native 1080p.

That being said, having a more consistent frame rate will make your experience better. Not having an input lag difference won't be a problem in single player games, as the difference will be under 100 ms anyway (F1 drivers have 200-300 ms reaction time) so it won't make too much of a difference.
