Half-Life 2 On Wine Is Faster On AMD R600g Over Catalyst
Lastly, for World in Conflict, the open-source driver runs much faster than using the closed-source Catalyst driver with Wine.
As far as why the open-source driver is outperforming the highly optimized closed-source driver, Stefan wrote, "I don't have an explanation for this yet, especially considering that fglrx beats r600g by a factor of 5 in most of your Linux-native tests. A possible cause is that my test setup is heavily CPU limited (usually 800x600 resolution, no multisampling). This was a conscious decision when I set up the tests because Wine's main performance issues are on the CPU side, not the GPU side. However, at least r300g's main problems seem to be GPU-related (not sure about r600g)."
I do have plans to conduct some Wine performance tests on my own in some different driver/hardware configurations. All of these Wine benchmarks shown in this article are Phoronix Test Suite test profiles that were written by Stefan for CodeWeavers and then uploaded to OpenBenchmarking.org for use by the community. So it is as easy as running e.g. phoronix-test-suite benchmark stefandoesinger/halflife2 to try out some of these Wine benchmarks for yourself.
