BTW, the Nvidia driver on Mac OS X offers OpenGL 2.1 (and appartently a bit of 3.0?), the Nvidia driver for Linux offers OpenGL 3.2 (as does the ATI driver), by the end of the month with the arrival of Fermi, make that OpenGL 3.3 and OpenGL 4.0.Snow Leopard, however, had performed quite poorly with the NVIDIA graphics due to the regression we pointed out earlier in this article. Hopefully the bug that is seriously hampering the NVIDIA OpenGL performance on Mac OS X when running at different resolutions will be fixed in the near future.
Lack of interest from Apple and/or Nvidia?
Not enough payments from Apple to Nvidia?
Work that has to be done on Mac OS X and not only the driver itself?
Big question is who writes this driver, Nvidia and/or Apple?
-And is it possible that Steam on OS X is going to push OpenGL development on that platform on the short/middle term? (I at least hope it does so, good OpenGL on OS X is good for OpenGL in general).
