Thank You – that is what I wanted to know.

Few more question please...

4.What about wine support for cards other then Geforce or Radeon? For
example, few month ago S3 released something called Chrome GTX 540 – with
full OpenGL 3.0 support – assuming drivers are not buggy, will that card
work well with wine? Will features like PS(Pixel Shaders) and VS(Vertex
Shaders) be supported?

5.If I remember correctly – before OpenGL 3.0 you could use PS only with
Nvidia hardware thought one of the extensions – did that change with the
release of OpenGL 3.0 – in other words, can you use generic OpenGL (NOT
vendor specific extension) to get GLSL and ARB to “emulate” DX Pixel and
Vertex Shaders? If so, are you planning to rewrite wine to use this generic
OpenGL instead of extensions?

Sorry for so many questions – but I REALLY would like to know.

Thanks again

Best regards
