Why does it matter if they are fake fps?

I don’t understand why the polemic. I’m not from this community and not really tech savvy other than understanding basic benchmarks so please explain.

If the 5070 does have the same fps that the 4090 what does it matter that half of them are ai generated if they are in real time and indistinguishable? Yes they are technically fake but performance wise you shouldn’t care? I don’t understand the polemic

I just bought a 4060 and I’m really happy with it dlss 3.5 is like fucking magic it’s not like the fake frames look unreal or are worse quality, or at least not in a way that my eyes can distinguish
