    because i do have mesa 10.2 git (from oibaf) and llvm 3.5 installed.
    Yes, you need to compile mesa against llvm 3.5. Additionally, you need a version of glxinfo that will properly report core profiles.

        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.
