I care about v-sync and the framerate being mostly stable, but that's about it.
We are so far into diminishing returns that I really cannot get excited about Raytracing, or 120fps modes, or 4k.
And while I think the Digital Foundry guys do interesting and thorough analysis, it comes off as increasingly asinine when they are zooming into individual frames to count pixels and point out differences in lighting effects. It also misleads* people into caring about things they otherwise wouldn't, and stokes fanboy flames.
Worrying about the framerate, or the lighting, is missing the bigger picture of what the game is like to play, what message its trying to get across, and how interesting the games world is to explore and play around in.
Those are the important things.
*Not trying to call the DF guys deceptive. They just put the info out there, people then mislead themselves.
