    Default R600 Gallium3D Expands On Stream-Out By Default

    Phoronix: R600 Gallium3D Expands On Stream-Out By Default

    The R600 Gallium3D driver is beginning to enable Stream-Out support by default for a greater selection of the Radeon graphics processors...

    Even better, most of the 6000-series Radeons are already supported by default. It's just the Cayman and up (6900's) that still have this turned off by default if my reading of the code is correct.

    How exactly does this benefit us?
    I.e., USE CASE.
    Explain.

    What you say is equivalent to saying "because it is better".
    What I am asking is "why does that make it better?".

    It's required for OpenGL 3.0 support. I think MSAA support (which Arlie had in an experimental repo) is the only other feature currently missing. (if you add S3TC lib and compile with float textures)

    Edit: 1 example i found on the web of it being used - http://prideout.net/blog/?tag=transform-feedback

    With it you can store what you generate on the GPU. Think deformable terrain for example, without having the cpu do transfers at any point.
