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.
Already planned to :PQuote:

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.Quote:

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.

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.

Performance is pretty much identical.
Wayland runs on everything but blobs. This driver has to do with google wanting Gallium3D on its chromebooks i think.Quote:
