DX9 Medium Quality
At 1440x900 using medium quality settings all four graphics cards tested are more than capable of delivering highly playable performance. The Radeon HD 3870 rendered an average of 50fps, though when placed in Crossfire mode the frame rates actually dropped quite significantly. Prior to the patch the Crossfire Radeon HD 3870 cards were rendering just 33.3fps which has now been increased to 41.3fps with the patch. The GeForce 8800 GT SLI performance went from 40.4fps to just 45.4fps so not much gained here then. The single card setups which includes the GeForce 8800 GTX/GT and Radeon HD 2900XT/3870 saw no performance gains when using the patch with these lower quality settings.
Increasing the resolution to 1680x1050 reduced performance only slightly, though you will notice that the 1.1 patch did help improve SLI performance a lot more here. As for the rest of the graphics cards nothing has really been gained here yet.
When jumping up to 1920x1200 we start to see a slight performance advantage going to the single graphics card setups when using the 1.1 patch. Although SLI and Crossfire are still slower than their single card configurations the performance gap has been closed with the 1.1 patch.
