Update: the "smooth edges" slider in Graphics Options was all the way on the Less end. Moving it towards More fixes this, but slows down the game something horrible. I know I didn't fool with the settings before; wonder what caused it to reset.

I had assumed Inteen was responsible because it's the only hack I have; I suppose it might be some custom clothing or makeup I downloaded.

Can InTeen cause the graphics quality to degrade? Because I have it on the highest settings; everything used to be crisp and clean, but since I installed the latest InTeen version, things have gotten noticeably fuzzier and there are stairstep artifacts on straight edges.
