Going from high down to medium detail has a profound impact on performance with the cards represented above. The GeForce 8600 GTS sees its performance reduced by up to 15% for instance. The Radeon cards generally see slimmer gains, but we think this is due in part because we conducted these tests under the DX10 path.
We’ve got more performance results with both the high and medium settings (including SLI results and shader model 3.0 cards like the X1950 Pro and X1650 XT) later in this article.
