Call to Action: Current plan for Windows Vista Aero will degrade OpenGL performance. Act Now to keep...-优快云博客

新闻转自OpenGL.org，微软计划在Windows Vista上把OpenGL置于Direct3D之上，这会使OpenGL性能显著降低，版本固定且无法扩展新特性。不过技术上可在不影响系统稳定安全下提供OpenGL ICD。OpenGL社区应鼓励各方维护其在Vista下的一流API地位。

以下新闻转自OpenGL.org.如果真是如此.重新BS MS一次. 看来我在Linux用OpenGL还是对的.至少不会一棵树上吊死.

很久前就看到了,没时间理,今天空一点,不管消息是真是假.我也旋宣传以下,支持一下GL.

不过我认为,ARB有办法绕过去,据不确定消息.MS其实也是把默认的OpenGL实现转给D3D.而并没有把厂商的ICD驱动给屏蔽掉.同时,还有个限制就是可能使用OpenGL的话，就不能使用Vista的花哨界面了。不过这个对我来说无所谓.我讨厌特别花哨的界面.简单可定制就可以。比如GNOME.我就超级喜欢.:)

Call to Action: Current plan for Windows Vista Aero will degrade OpenGL performance. Act Now to keep OpenGL a first class API under Windows

Microsoft's current plan for OpenGL on Windows Vista is to layer OpenGL over Direct3D in order to use OpenGL with a composited desktop to obtain the Aero experience. If an OpenGL ICD is run - the desktop compositor will switch off - significantly degrading the user experience. 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 Aero experience without compromising the stability or the security of the operating system. Layering OpenGL over Direct3D is a policy decision more than a technical decision.

The OpenGL community should encourage hardware & software developers, as well as Microsoft to maintain OpenGL as a first class API under Windows Vista.

What can you do?:

Write to your preferred ISV, hardware developer, video card manufacturer or OEM and tell them to bring this up with Microsoft (e.g. 3Dlabs, ATI, Intel, Matrox, NVIDIA, HP, Dell). This will be the most effective action you can take.
Bring this issue up on other developer and tech-related web sites. If you have a personal blog or podcast, talk about the issue there. Windows Vista might end up being a great product, but not if OpenGL is crippled
