Further Testing Shows More Hope For ATI Gallium3D
At 1920 x 1080 in World of Padman for the X1800XL, X1800XT, and X1950PRO there is a major finding: the newest ATI Gallium3D code for these GPUs are faster than Catalyst! Again, without any noticeable rendering problems for either driver. When looking at the composite for the three ATI graphics cards here, the newest open-source code with KMS page-flipping, color-tiling, and disabling swap buffer waits is nearly 3x faster than the stock Ubuntu 10.10 packages. The newest code using the R300g Mesa driver is 19% faster for its three-card composite than Catalyst 9.2.
Urban Terror is the last game tested in this article that is compatible with the open-source Mesa driver stack. With this Linux-native game, the newest code was just 13% faster than what is found in Ubuntu 10.10. The Catalyst driver was 33~34% faster than this newest open-source code, which is similar to some of our findings in other test results.
