The source engine? I see a lot of it in UT2004, HL2, FEAR, and Doom 3. I never really noticed it until I read about it, and when I set image quality to high quality, it looked SO much better, but at the cost of FPS. Yes I have a SATA optical drive. At the time I got it, it was the only one that had 8mb of cache.beedubaya said:003, you seem really bothered by that AF shimmering in the Source engine. Honestly, I barely noticed it when I had my 6800GT, and the only game I saw it in was CSS. Its not worth making that big of deal out of.
