    Phoronix: Intel Gallium3D Gets sRGB Textures

    The Intel "i915g" Gallium3D driver now implements sRGB textures support, but this is basically the end of the road for new features...

    Hey Michael, how about re-benchmarking i915 gallium vs classic?

      915 with OpenGL 2.1? Wow. I didn't know the hardware was capable of that. Thought you needed Gen 4 hardware for that. Mesa and Windows are on OpenGL 1.4.

          I'll try it on a 915GM as soon as it hits the oibaf PPA.

          On that laptop, HP Compaq nc6120, 3D acceleration is somehow very choppy with both Mesa and Gallium. But that's maybe because it still runs Mint 11 with Linux 2.6.38. Linux Mint 13 Cinnamon from a Live DVD runs quite well on the old gpu so maybe that newer version will also have faster glxgears.

            It' helps intel driver to run wayland?

              Nice to know that there's a i915g PPA. I thought it was just for cutting edge Mesa.

              I'm stuck on a 945gm for a few days as my laptop is repaired. Gonna give this a try to see if it performs any better than classic.

              OpenGL vendor string: VMware, Inc.
              OpenGL renderer string: Gallium 0.4 on i915 (chipset: 945GM)
              OpenGL version string: 2.0 Mesa 8.1-devel (git-6404095 precise-oibaf-ppa)
              OpenGL shading language version string: 1.20

                @LLStarks: Intel i915g is included in the PPA but not automatically enabled. Instructions on running a program with Gallium3D rendering are in the PPA's description.
                https://launchpad.net/~oibaf/+archive/graphics-drivers

                Note that i915g is only for 91x/94x hardware (GMA 900 and 950 aka Gen 3; correct me if I'm wrong) and not for newer Intels.

                    Wayland runs on everything but blobs. This driver has to do with google wanting Gallium3D on its chromebooks i think.

                      Your numbers show about a 25% increase, it's just that the hardware is so slow that doesn't appear to be much.

                        There are a lot of things on todo.txt,but I don t know if stephane will continue the development.
