Windows I have been both a Windows and Linux user for a long time (I started with Windows 3.1 and RedHat 5.1 kernel 2.0.x if I recall correctly) and have stuck with both for various reasons. I'm writing this article not as a DIY lofty vantage platform by which I can bash MS nor as a 'Why you should switched' flame bate piece, but have tried to keep an open mind and reflect the actually experience that I have had with Vista so far, regardless of OS political propaganda. Please keep in mind this is still an opinion piece and most probably to be taken with a pinch of salt.

RE: What about OpenGL degradation?

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.

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.

It is different. It is stuck at OpenGL 1.4, when the rest of the world is on OpenGL 2.1
