What's the lowest level of graphics you still find acceptable?

It's an interesting question because I can play the best 2d games and even if I'm not interested in them; it's most likely not because of the visuals.

But for 3d games... For some reason it's different. My standards are higher. Probably 7th gen 360/Ps3 level is the worst I'd prefer. Although if it has a good art style then Ps2/Xbox/Gamecube games are perfectly acceptable.
