    That's strange that WoW doesn't render correctly for you. It works for me on my 4850.
    Player models aren't all messed up or anything. I used to have that problem, but it went away after going to the latest Mesa and doing all the stuff to enable S3TC including using the kernel from drm-radeon-testing.

    The only problems I had with WoW was the performance wasn't that good (10-20fps), and the icons for items and abilities would sometimes not render correctly. And going underwater gives you a psychedelic view.

      I'm using the edgers ppa 2.6.38-4 kernel.
      I don't have enough space to compile the kernel myself unless I can do it from an ntfs drive.

        Yeah, you need to use the kernel in the drm-radeon-testing branch from here
        It has one change that you need for s3tc that hasn't been merged into the mainline kernel yet.

          S3TC does not work for me. I am using r600g from mesa-9999 (compiled with R600_ENABLE_S3TC=1, USE_EXTERNAL_DXTN_LIB=1), xf86-video-ati-9999, libtxc_dxtn-1.0.0, drm-radeon-testing (2.6.38-rc8-44191-g38f1cff), libdrm-9999 and even wine-9999, all checked out in the last hour and...

          Code:
          glxinfo |grep -i s3tc
              GL_NV_texgen_reflection, GL_NV_texture_env_combine4, GL_S3_s3tc, 
              GL_EXT_texture_compression_s3tc, GL_EXT_texture_env_dot3,
          but...
          1. L4D is one green screen: http://img816.imageshack.us/i/l4d.png/
          2. L4D2 doesn't start: "I need compressed texture support blah blah": http://img560.imageshack.us/i/l4d2.png/
          3. NWN and native Unreal Tournament look like some distorted, multiplied slices: http://img192.imageshack.us/i/nwn.png/


          some weeks ago it worked, but I don't know how and why this changed, but the result obviously sucks

            For problem number 3 : Disable color tiling, it will fix it. (Have the same unresolved bug here)

              It's a pre-S3TC screenshot but it's the same issue.

              PS : Why the edit limit is less that one minute? I did not get the time to remember the screenshot url...
