Well that depends entirely on where you look and what you choose to ignore, there are plenty of people who say DLSS 3 is great and works well, not just on this forum but by several reputable sources too, even bang 4 buck (who owns all top end hardware values it) i.e. by people who have no need to justify their purchase as they either can afford it or/and didn't pay anything for it in the first place. Now if you tell me that you're trying to run FG on a 4060 at 4k where base fps is like 20, well yeah, FG isn't a miracle worker.... Depending which ada gpu you bought, ampere owners will have got an upgrade overall, even if they bought the same tier of gpu.
@TNA how much faster is your 4070ti compared to your previous 3080ti at your res again? Not even factoring in frame gen.
Also, if the polls recently on native, upscaling etc. are anything to go by, turns out people don't even use nor want software solutions to improve fps therefore surely it isn't a factor when buying these new gpus?
I do agree though, FG as a whole is somewhat still too new/beta, as in, for best results, you need to be getting 50-60 fps already. My experience with the 4080 on geforce now was fantastic, even the lag wasn't a huge issue and that was on cloud streaming.... AMDs FSR 3 official integrations have been awful and being locked to fsr upscaling makes it a no go for many, even amd owners as shown. The mod injector method is hit and miss so again, much like other technology, to experience the best as of "now", you have to pay that premium. Personally for me, it's akin to turing when dlss and rt came about, there simply aren't enough demanding games to really justify the need for FG yet, CP 2077 is the main one and I've already completed that 3 times now so meh and AW 2 ran fairly well given slow paced game so by the time there are more games where FG will be necessary, we'll have the next gen series out, which will be even better and probably have something else extra.
EDIT:
Also, nvidia made it very clear in their benchmarks/pr slides what the performance was without FG so it wasn't even a case of misleading the crowd unless again, people only look at bars and nothing else. AMD on the other hand when it comes to their PR/slides, well... the less said the better.
