    is there any reason 9.2.5 is smooth on source games yet 10.2 is juddery and almost half the FPS?

      Yes, you need to compile mesa against llvm 3.5.
      Is AMD starting to regret requiring llvm for new driver versions yet, given how slowly everyone upgrades? Or do you still think it was the right decision?

Best would be if mesa developers could make it disabled by default when compiled in and only enabled with an env variable. This way I could enable it and who want to try it could set the env var.
        So since now LLVM backend disabled by default:

        Can you please enable it in your builds? Thanks.

          • Anyone know how to disable vsync in ubuntu? The "vblank_mode=0" gives a noticable performance increase in terminal, but I'm trying to make it global for every application I run.

              add just that, as one line, to /etc/environment

                • Don't forget to disable swapbufferswait in xorg.conf.

                    according to that news and the forum discussion to the news it seems not to be a good idea to do so. not only has it compatibility issues it also seems to be slower.

                    beside of this it is possible to enable it via an enviroment virable.

                    it does sound good to enable it by default.

                    • Only software render unity with intel 4000

                      Hello,

                      just updated my Ubuntu to 14.04 and refreshened my drivers from Oibaf PPA, now I only have sofware render at Unity.

                      I have a Dell XPS 13 Ultranotebook (intel 3rd gen CPU - HD 4000 graphics).

                      Here is the test from unity:

                      # /usr/lib/nux/unity_support_test -p
                      OpenGL vendor string: VMware, Inc.
                      OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.4, 256 bits)
                      OpenGL version string: 3.0 Mesa 10.2.0-devel (git-48fc270 trusty-oibaf-ppa)

                      Not software rendered: no
                      Not blacklisted: yes
                      GLX fbconfig: yes
                      GLX texture from pixmap: yes
                      GL npot or rect textures: yes
                      GL vertex program: yes
                      GL fragment program: yes
                      GL vertex buffer object: yes
                      GL framebuffer object: yes
                      GL version is 1.4+: yes

                      Unity 3D supported: no

                      This is the Xorg.0.log data: http://paste.ubuntu.com/7275610/

                      Any ideas?

                      Thanks
