    It seems perfectly reasonable to recommend drivers that work better with your software, but the fact that the bugs and performance issues were identified but never reported seems... very odd.

    Would you expect the open-source driver developers to recommend other comparable games which work fine?

      No. But we can expect "Wont fix" if its in fact bug in engine.
      Though that one patch mentioned seam to be related to book keeping of internal structures.

        Try going to http://www.shadertoy.com and watch the open source drivers implode....

        These should serve as a basis for improving the oss drivers.

        I'm not an NVidia fanboy; I'd like Sandy Bridge to work well - its just that it doesn't...

        Believe it or not but the Linux Catalyst 14.12 driver survives the renderings when visiting this site on my system. Was kind of expecting it to crash and burn.

          I wasn't involved in the process of writing the initial announcement otherwise I would have asked to remove the note about proprietary driver.

          Mesa drivers run STK fine here with Hawaii last time I tested. There is a bug that was uncovered during development (about texture array framebuffer) and there is a patch (against mesa) to solve it (I didnt commit it since the corresponding piglit patch need some work but I intend to do it before final stk release in january or february).
          Proprietary drivers support newer features like compute shaders that I use to improve some filter's performance when supported but I had much more stability issue.

            Good to know! I guess STK will then be one of the games I'll try playing once I get my gaming rig back this weekend
            Here's hoping it will work on R600g Cayman or RadeonSI Tahiti-LE ...

              I am very sorry - I did not mean to crash your system.

              I tried it on baytrail and ivybridge and it just took forever to load.

If there is a Linux x86_64 binary though, all the better as then PTS users can avoid potentially needing various external dependencies for the devel packages to compile from source as most users likely don't have all the necessary dependencies installed by default and PTS can install them automatically but then I need to make sure they're available on the 12+ distributions of tier-one support.
                I see. Sorry for being so harsh earlier. My apologies.

                  I wanted to add some precisions. Like we said in our original blog post not all tracks are converted and you tested only "old tracks" that where minimaly ported to the new engine. To test the new engine in all it's glory you should try the track Gran Paradiso Island or Cocoa Temple. These are using the new engine.

                  This is a screenshot directly taken ingame


                  You can unlock them by playing the story mode or by editing the file players.xml and replacing all solved="none" by solved="hard" (see this http://supertuxkart.sourceforge.net/...config_file.3F) to locate your players.xml

                  Have a nice race

                  I've just done a quick test on a R280x with latest stable mesa (ie 10.4), and things work ok till I turn on Dynamic Lights.
                  Then whatever is dynamic is just black...
                  Not sure where the issue comes from though.

                  There are many errors in the terminal:

                  I looked into the missing png files, but they are installed, so not sure, maybe installed to the wrong place?

                    For me everything is broken in some way on both linux with radeon or fglrx drivers. And on Windows too

                    I don't wanna fill 30 bugs about that, it is alpha software and developers should know that

                      Hanged my intel windows machine too, no idea which gen it is.
                      Works fine on r600g...
