Care and know are 2 different things. If the settings to make a game look better were fairly accessible (easy to understand) to the average gamer, they'd care. No one likes jaggies or their eyes to hurt.
Well, correct, but what I was trying to point out is that tons of people still play new games at 1024x768, and that's not a bad resolution to them - with AA turned on, there aren't jaggies either. And I'm talking about people who understand the concept of resolution.
