Just wanted to let you know that the 10.8.4 seems to bring another significant GPU driver upgrade. My score in Unigine Valley is up 8% (from 590 to 640). Now to compare it to the scores in Windows... will do it some time later.
Update: Windows 7 x64 benchmarks, Unigine Valley, same settings (1680x1050, Ultra, no AA)
DX9: 771
DX11: 649
OpenGL: 551
As we can see, the OS X drivers are still quite a bit slower than the DX9 version of the benchmark under Windows (~20%). Although, OS X performs much better than the OpenGL version under Windows. Weird thing: when running the GL version of the benchmark, the GPU temperatures are significantly lower on both OSes, so is the VRAM clock. I wonder whether there is some problem with the code of the benchmark, or with the driver - which prevents the automatic overclocking from working. We are talking about 500Mhz (25% OC from the base), so its a pretty big deal! Would also explain the discrepancy between the DX and GL benchmarks...
