    Are you sure for pixel shader 2.0 ?

    @Velcro_SP

    Thanks for the info.

    @MorphOS Team

    Why not add this info in the MorphOS 2.5 release notes ?

    Actually, you misunderstood that, I think ... XGI Volari drivers for MorphOS do not support 3D currently. Pixelshader 2.0 is some concept introduced with Direct3D (which is supported by Volari hardware albeit at some "entry level" performance) but currently MorphOS does not even have any sort of Direct3D compatiblity layer ...
    If you need MorphOS 3D support, you have to go with Radeon cards for now.

    I think OpenGL is another way to use this hardware functionality, at least the pixel shader entry on Wikipedia says this.

    OpenGL still depends on the actual HW drivers to provide the support for the pixel sharers. Thus even if particular OpenGL implementation would support pixel shaders, it still doesn't mean that they'd be available for any given configuration.

    Actually, newer OpenGL versions have a similar concept but "Pixelshader" and especially "2.0" support originates from Direct3D.
    Of course OpenGL hardware drivers can make use of that but it doesn't translate 1:1 to OpenGL's concepts of fragment/vertex programs and it's higher abstraction shading language ....
    AFAIK, public MorphOS 3D still uses the fixed function pipeline introduced by OpenGL, so the actual shader support doesnt really matter. This will most likely change in the future, though.
    Originally, I just wanted to point out that Volari cards were not that far behind feature-wise, since e.g. Radeon 9250 cards don't even support Pixelshader 2.0 afaik, at least with the standard (win32) drivers.
    Anyway, my point that you better go for a Radeon card if you want MorphOS 3D, still stands .....

    Probably a little bit OT but what happened to a new 3D drivers which were written by BigFoot and even presented at some stage?
