Agreed, I just don't see enough difference to tell which is best, unless, as you say, there's graphical artifacts that we're not aware of, it's just preference at this point. Pick your preference and call it a day I say.With realistic lighting engine comes realistic headache matching the lighting for comparison. These are all real photos that look like shitty game graphics for example:
So I wouldn’t waste my time trying to compare between DLSS and FSR. Unless specified by reviewer that there's graphical artifacts both perform similarly at this point. And if one performs poorly compared to other, it's developer side.
Ultimately I think in the future DLSS is gonna get silent death like G-sync.
