One of the fun things about being a hardware analyst is that every now and then, research and comparison between products turns up something both interesting and unexpected. In this case, we were testing and comparing image quality between ATI's 5970 and the GeForce GTX 480 as part of a system review when we stumbled across an officially confirmed antialiasing bug in NVIDIA's 197.41 drivers. Unlike some "bugs" that artificially inflate benchmark performance or lower detail levels, this one improves image quality by performing supersampling AA (SSAA) across the entire image...
