RE[2]: What about OpenGL degradation?

OpenGL on Vista is no different than on previous versions of Windows. Vista continues default acceleration of OpenGL via D3D which was introduced in Windows XP. Vista also continues support for OpenGL ICDs that allow for direct hardware acceleration and support of IHV-specific features and extensions.

My understanding is that Vista is Microsoft's way of trying to kill off SGI and OpenGL in the marketplace (and beating up on Mac/Linux at the same time).
I've read there is no default/any OpenglICD for Windows Vista, instead, all calls being run through directx 10, which is WRAPPING the calls... and then getting a 50% or more degradation of performance.
ID Software, most FP-Shooters, many flight sims, etc., should all be howling mad over this. It's a huge blow to Vista, and one that I think may keep people away.
