    Phoronix: A Pleasant Surprise In Mesa 8.1 Radeon Gallium3D

    When running some tests on the latest Mesa 8.1-devel Gallium3D code-base for the "R600" Radeon Gallium3D driver, I was surprised by some of the results...

    Needs more windows(wine) games tests.

    Needs more windows(wine) games tests. Now that would be a surprise. Been hoping for it for quite some time now. Using Mesa 7.9 on x1300 mobility, WoW runs. Using mesa 8.0 on Evergreen hardware (Juniper), it doesn't.

    Since wine is doing better with every release, and games start working more and more (Skyrim, Crysis 2, Dragonage 2, albeit using blobs), we should see how Mesa handles windows games.

      Why? Skyrim renders extremely well on Open Source radeon. The frame rate seems not to be jumpy, but it is still very low. But on low settings it actually is starting to get playable: http://www.youtube.com/watch?v=2LDAd_oFzgU
      There are also videos of Crysis 2 on Open Source radeon that don't look that bad: http://www.youtube.com/watch?v=XZ_T_xepfW8

      It would be nice if those games could be benchmarked by the phoronix testsuite but I guess they would need free to play demos with FPS measurement for that...

        Well, Just yesterday I tested out Mesa 8.0 on Arch with 3.2.7 kernel, HD6770, i3-2120, it didn't work. Anything i'm missing out?

            Don't tease me. I lost half my day yesterday testing out mesa 8.0 Anyway, at least for Wow, the same error that was prior mesa 8.0 is here as well (at least on evergreen hardware). I only need Wow to work... (not for me. for my wife :|)

              I have played WoW on Evergreen, and Fallout 3, Bioshock, Crysis etc. If it doesn't work for you it's either a regression or possibly something hardware specific (I'm using Redwood not Juniper).

                @phoronix, two advices for openbenchmarking.org. You might want to change the mouse to a pointer when someone hovers over one of the tabs, and on the tab 'compute performance', you should fix 'runnning' and 'Phoronx'.

                  Can you specify Mesa/wine version? I can't even launch Wow. There's a weird error #132. Same wine, same prefix, works with blob, doesn't work with Mesa. Tried WINEDEBUG, nothing relevant.

                    I don't recall exact versions (I'm mostly running stuff from git) but it shouldn't matter.

                    You might want to make sure that you have the proper drivers (especially if you're on a 64bit system).

                      Is this with 2D tiling enabled in DDX too ? Right now mesa 8.1 will enable 2D tiling for texture even if not enabled in the ddx. You can test without 2d tiling set R600_SURF=0 for that (default is 1). Anyway if you enable 2D tiling in the DDX too you will get a bigger boost (depends but vary btw 1% to 5% on things i tried (nexuiz arena tuxracer) compared to only 2d tiled texture)

                        Skyrim? Well, the 6550M is actually a renamed HD 5650M and thus Redwood. I don't have any Cayman card to compare. But my suggestion would be running your stuff with
                        Code:
                        LIBGL_DEBUG=verbose WINEDEBUG=-all wine foobar.exe
                        This should hide all the wine debug output (which also should make wine a little bit faster) and also display whether your 32 bit mesa is actually used.

                          Update on the Wow thing

                          So, funny story. I was tricked into testing again, but this time, I didn't use the mesa bundled with Arch, yet an unofficial repository with mesa-git. Wow runs with 30FPS on Ultra quality on an HD6770. Apparently the bug is in Arch packages, not mesa itself.

                          Thanks for the push, guys!

                            But another problem arose. Running dual head, completely distorts the desktop with xf86-video-ati-git.

                              Heroes of Newerth

                              You could also do some Heroes oh Newerth Benchmarks!
                              Im still not sure if i should buy a AMD E-450 Laptop, cause i dont know if this game would run on such a device.

                              Heroes of Newerth is free to play and has a native Linux Client! (also a Windows and MacOS 10 Client)
