I value good graphics a lot; the better the in-game graphics, the more visually engaged i am. In turn, that makes me enjoy a game more than i otherwise would. Despite that though, i don't really have a point beyond which i don't consider a games graphics acceptable. A good game is a good game, regardless to how many triangles it can poop out every second.
I do struggle with image quality though. Likely for the same reason that good in-game graphics visually engage me more, i find the effects of lower-resolutions and poor AA (blurring, jaggies, etc) incredibly distracting. If the resolution is really low (sub-720p), i often get headaches are an hour or so of play. To be honest, it can be pretty irritating. FF15's variable resolution of 900p to 1080p, coupled with its very aggressive temporal anti-aliasing (which does a great job of killing jaggies, but makes the whole game look blurrier than it should), has been enough to make me put off playing more of it for a few weeks, and to buy a PS4 Pro this month rather than my original plan of February/March.
That said, image quality won't stop be playing a game. If i have no choice but to play a good game with pixels to size of apples, then so be it. If it's really bad, i'll just play it in smaller doses (which is what i recently did to play RDR).
I should note that my gripes with FF15 are larger than they'd be if the Pro didn't exist (or wasn't releasing for months). I'm happy the choice exists, it's simply that my desire to play the game with better image quality is slightly larger than my desire to play it now versus in a few weeks.
