    Phoronix: VC4 Raspberry Pi Driver Gets Job Shuffling For Faster OpenGL

    Those making use of the VC4 Gallium3D driver for open-source Raspberry Pi OpenGL support will want to pull down the latest Mesa Git code if you are interested in double-digit performance improvements for at least some OpenGL workloads...

    I don't suppose there are any good benchmarks you could use to show the difference between this and their blob? I know it only supports GLES 2 which is why i am not sure.

      Isn't it supporting quake 3 or similar? I seem to recall something about this. I would be interested in some performance figures as well.

      Could someone enlighten me on those topics, please: Is it usable yet? Is there some video decoding acceleration of some sort?

        Last time I tried it worked for desktop, I think. There have been videos of people playing Jedi Academy on it on Youtube so it should work for some 3D as well.

        There is a bug report tracking this, but not much progress there: https://github.com/anholt/linux/issues/13
        Camera is a bit closer to be working (you didn't ask this, but someone else might): https://github.com/anholt/linux/issues/12

              It supports OpenGL 2.1 but is buggy from my experience. OpenCity doesn't display the terrain, TORCS has really bad performance, Lincity-NG has graphics corruption when scrolling.
