More Microsoft Shenanigans

Expect OpenGL in Vista to be approximately 50% slower than DirectX (made deliberately slower my M$). From the posting:-

• OpenGL performance will be significantly reduced - perhaps as much as 50%
  
• OpenGL on Windows will be fixed at a vanilla version of OpenGL 1.4
  
• No extensions will be possible to expose future hardware innovations

More here at the Wikipedia article:-

Microsoft has taken the decision not to release the information necessary to allow third parties (such as those at NVIDIA, ATI or the other large graphics card manufacturers) to develop replacement drivers, leaving no way to avoid the 50% speed drop.
