Windows Vista May Degrade OpenGL

Posted by ryuzaki0 on from the you-have-chosen-poorly dept.

srw writes "OpenGL is the industry choice for cross platform, hardware accelerated 3D graphics, and it is also the only way you can get fast 3D graphics on your Linux desktop. It now seems Windows Vista implements OpenGL via Direct3D, seriously degrading its performance and attractiveness to developers." From the article: "In practice this means for OpenGL under Aeroglass: 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. It would be technically straightforward to provide an OpenGL ICD within the full Aeroglass experience without compromising the stability or the security of the operating system. Layering OpenGL over Direct3D is a policy more than a technical decision."

    Does anybody else not believe this at all? I think this was totally blown out of proportion by the opengl guys and the real situation is going to be nothing like this. Of course, nobody on Slashdot is going to read the article anyway and the hyperbole is just going to grow and grow...

    Particularly fascinating that with all of the (formerly) core features that MS has been dropping from Vista, they still somehow find time in the development schedule to screw over an open standard like OpenGL.

    WinXP SP3 - Now with fewer features and less compatibility than ever!

    That's a very Eurocentric view. Even if the governments decide to go OSS, that's ony a portion of sales in any region.

    MS would be smart to make a EU specfic version again, if only to keep out of the courts.

    Ehm...

    Isn't this a bit like going back to the age of Windows 95? That release didn't have an OpenGL driver, but nobody cared. It only came standard in Windows with NT 4, if I'm not mistaken.

    But still, if you look at the standard OpenGL implementation in Windows nowadays, you'll notice that it's still basically crap.

    "But why does Doom3 run at all", you might ask?

    Well: because it's the hardware vendors who provide the driver. A major graphics chip manufacturer can't afford not to have a decent OpenGL driver. So, nobody will care if MS doesn't want to implement a decent driver. Nvidia, ATI & the others will put out a driver, as has always been the case...

    So, stop worrying, then!
