Dario, thanks for the 8600M rendering info follow-up!
With the two current shipping "next-gen" graphics cards from Ati HD in
the iMac and the NV 8600M in the MBP, is there differences in the
functionality between the exposed SM4.0/GL2 functionality in these two
cards?
8600M has support for,
GL_EXT_geometry_shader4
GL_EXT_gpu_shader4
GL_EXT_transform_feedback
and vertex texture fetch
GL_NV_vertex_program3
What about Apple's driver support for ATI Radeon HD cards??? Anyone with a
HD iMac want to post the supported GL extension list?
My hope is that Apple is providing the same SM4.0 support (or at least
SM3.0 vertex texture fetch support) for both the HD and GeForce 8 cards.
Sure would demonstrate the advantage of Apple providing their own graphics
drivers! From what I have gathered from other forums, ATI's GL drivers
(windows/linux) for the Radeon HD cards have NO support for SM4.0
features and also are still missing any support for vertex texture fetch
(SM3.0 feature).
