    Too bad, no OpenGL 4.3 support.
    OpenGL 4.0 support is only for their Windows driver. Linux will be lucky to see OpenGL 3.3 support before the end of the year.

      It's still a mystery to me if OpenGL support has to do with hardware capabilites or if it's just a driver thing.

        Both. You get the lowest version both support.

          OpenGL 3.3 is definitely going to be finished this year, at least for the Intel driver.

            Now I don't know how much work GLSL 1.50 is, but is it more than half a year's work?

              At least some of the patches required for GLSL 1.5 support have been sent to the mesa-dev list (and a fair while ago too). I don't know if they were all the required patches or not, somebody who actually writes these things would need to comment :-)

                It's basically Geometry Shaders and Interface Blocks. Interface Blocks are basically done, and Geometry Shaders are coming along quite nicely. We're actually able to run fairly complex geometry shaders on i965 now.

                  Do you have plans for supporting OpenGL 4.1 on Haswell gen hw ? :P (Ok I know, I should laught from PR department not you, but still )

                    @Kayden

                    When will Rage/Doom 3 BFG run with mesa? How much faster would be mesa git compared to 9.1 for Ivy Bridge and Left 4 Dead 2? Team Fortress 2/Half-Life 2 DM was basically playable but L4D2 is too slow (around 20 fps @ 1920x1200).

                      Not right away, obviously...but I imagine we probably will at some point. Is there a specific feature you were hoping for? We can always implement certain extensions before finishing a full GL version.

                      I don't know about Rage/Doom 3 BFG at this point...I haven't had time to look into it yet (sorry). L4D2 is perfectly playable on my Ivybridge (Lenovo X230) with Mesa master at 1920x1080. I haven't tried 9.1 lately, but we have done a bunch of optimizations since then, and I'm seeing a lot more than 20 fps. You might also try turning Shaders and Effects down to Low, if you haven't already.
