Have a friend getting into PC gaming

Like I said earlier, SHOW HIM THE DIFFERENCES. You can explain things like Anisotropic Filtering all you want, but who is going to sit there while you talk about texture rendering at a distance when being viewed by the camera. You could even find websites that point out the difference if you don't want to do it in-game.

just type in google "what is" followed by the thing you're looking for. Lots of websites have pictures showing what AA and AF are.
