With these settings, it's possible we're system limited with this benchmark. The 1 fps difference between a single Radeon X1900XTX and two Radeon X1900 seems to support this. We're also saw some strange differences - unlike the other games, with Serious Sam II we're seeing a difference between Super AA 8x and 10x performance. In fact, Super AA 10x performance in on a par with Super AA 12x and 14x. In all honesty, we don't think Serious Sam II is contributing any useful information. Let's move on.
