    Phoronix: LLVMpipe & Compiz 0.9 Still Don't Play Along

    LLVMpipe is an especially interesting Gallium3D driver since it allows accelerating the state trackers atop any modern CPU, but for any close to decent level of performance when using OpenGL you need a hefty multi-core CPU (here's some LLVMpipe benchmarks just from last week) that supports the latest SSE4 instructions as well. While some OpenGL games will run with LLVMpipe and the performance of this driver that leverages the Low-Level Virtual Machine is much faster and better than Mesa's old software rasterizer or the Gallium3D Softpipe driver, Compiz nor the GNOME Shell (and most other compositing window managers) yet work with this driver...

    Would've hoped for a screenshot of the current state

      Funny that it dies on the window decorations.... we get the same thing with poulsbo and have the same missing extension. I wonder if the DECORATOR is still requiring the texture from pixmap extension?

      Note: poulsbo does compiz with Option "ExaNoComposite" "true".

        It seems to me as if running a compositor on a software renderer is a useless waste of CPU cycles...

          As I pointed out in the last thread there is a patch to add TFP support to llvmpipe/softpipe/etc.:

            Unless, you know, you care about functionality. This same logic would also apply to running a graphical environment in general.
