Resolution Comparison
The Crysis 1.1 patch only improved the GeForce 8800 GTS 512MB's frame rate by about 1.5 fps across all resolutions. While it helped nudge the frame rate at 1280 x 1024 to 35 fps, it was hardly a significant improvement in performance. When we combined the results, this is what we found :
As you can see, there was a small but noticeable boost in frame rates at all resolutions. However, the improvement was not significant enough to really matter. Crysis was still not playable at 1600 x 1200 at the High setting even with a system built around the high-end Intel Core 2 Extreme QX6700 quad-core processor and the new NVIDIA GeForce 8800 GTS 512MB graphics card.
Anti-Aliasing Comparison
The anti-aliasing results were not very consistent. We had to run the test many, many times (at least a dozen runs) and used the highest results from the whole set.
With no anti-aliasing, the performance boost was only 1.4 fps (6.5%) at 1920 x 1080. At 2x AA though, there was a large 3.2 fps (29.4%) boost in frame rate. At 4x AA, the performance advantage was 1.9 fps (28.8%).
