Graphics may matter that much to you, but not to me. I cannot relate to this conception of immersion some of you guys have. To me, videogames look like videogames. They may exhibit visual artifacts, pop-in, etc., and I expect that in even the most polished games, like
Super Mario Odyssey. It's what games do.
I don't care about jaggies, because it's not like I ever forget the image is composed of pixels (or that I'm looking at a glowing rectangle in my living room). I'm not mocking you as if I think you can't tell the difference, I just don't really understand the quest to make pixels imperceptible.
I think anti-aliasing accomplishes almost nothing; higher resolution is nice for clarity, and that's about it. I still play 480i games with a de-interlacer to my 28" HD monitor on a regular basis. My soft-modded Wii is an emulator box.
When I'm immersed in a game, I derive that immersion from gameplay, worldbuilding, good physics, a relatable protagonist, attention to detail, stuff like that.
I can be just as immersed by a Wii fantasy JRPG or a side-scrolling SNES game as a photorealistic PS4 game. Graphics do matter, but more in an artistic sense than technical fidelity as far as I'm concerned. For what I care about, PCARS2 is hardly different from PCARS1, and is still a great-looking game.
