Okie, sorry if this has been posted before, but I'm rather desperate to know:

I've seen many beautiful pictures from the Sims 2 - lovely graphics, nice, smooth edges, beautiful lighting, etc. But mine always turn out pixelly and sort of weird. It was Buffy's shots, specifically, that made me wonder. Is it just because my graphics card sucks? Or is there a setting on the game that I can change to improve this?
