    Thanks for your hard work, Michael.
    I wished your work would be more appreciated by the corporates.

      I guess many people will be really annoyed by my proposal, but I'd really like to see some present and past heavy-weights like:

      3DMark 2006 (running in Wine, of course)
      StarCraft II (ditto)
      Fallout 3 (ditto)
      Counter Strike Global Offensive (native)

      The games you're currently testing are inconclusive in regard to modern GPU requirements.
      First point is that these titles are not linux-friendly at all. Wine is not a viable option for many of these titles. It costs a lot (and I know what I'm doing, I tried).

      Even if we were able to run it confortably, or even better native linux support, a major issue stays : you can't get them automated, even more if they are available through steam. Just remember how PTS works : it downloads all the stuff the profile selected need through distro repositories. Hence no closed-source games can be found there.

      Maybe you can help with that, by trying to open game publishers' eyes. You'll have to deal with shareholders, that only see cash and DRM. Good luck.

        The annoying thing is the fact that you asked a question that has been asked a bajillion times already in basically every GPU test Michael has made for the past couple of years, even though there are explicit reasons more "tangible games" are not involved.

        Ironic you mentioned 3DMark, SC2, and F3 as being more tangible games, considering running them (in wine) would give you completely useless scores due to wine's ever-changing nature. While they are more graphically demanding, they still don't take advantage of modern hardware due to wine's graphical restrictions. The only wine tests that should be done are benchmarks between other versions of wine and that's it. That being said, it would actually be nice to see PTS benchmarks in wine. So basically comparing the same test between windows, linux, and wine.

          Closed-source games can be found there...

          http://openbenchmarking.org/test/pts/doom3
          http://openbenchmarking.org/test/pts/etqw
          http://openbenchmarking.org/test/pts/quake4
          http://openbenchmarking.org/test/pts/prey
          http://openbenchmarking.org/test/pts/unigine-valley
          etc....

          It's also possible to test wine games:

          http://openbenchmarking.org/test/ste...nger/tmnations

          PTS only relies upon distro repositories for test dependencies, e.g. downloading GCC or some library, but all of the test codes/programs themselves are downloaded directly from upstream sources. I have no issues with testing closed-source games, I just care that they can be automated well and deliver reproducible and accurate results.

            Michael,

            Thank you for the testing! Very interesting results. I'm seriously considering moving off the Catalyst-Legacy (w/Ubuntu 13.04) to the Radeon Driver and Ubuntu 13.10 for my HD4200. I'll try and benchmark it.

              I do not understand Alex possible explanation concerning GART. I thought that this feature has disappear long ago. With the last system having GART are over 10 years old.

              The only thing that I am aware is the i915 driver that have a fake GART driver. Is the radeon driver is using a similar trick?

                Are you sure about that? It seems to be between 60-90% on average on 6950.

                  Somehow I get the impression that cheap gpus run well and expensive ones run bad.

                  I tried to use the open source driver for my hybrid HD 7970M.

                  Auto poweroff ("runtime pm") does not seem to be in 3.12 yet. It's pretty important because with vgaswitcheroo if you power off the radeon gpu in X and then go to a tty and then back to X, the driver locks up.

                  With DPM enabled:
                  When starting X on boot it locked up with a cursor in the upper left corner. Starting X a little while after boot worked.
                  When powering off the radeon GPU with vgaswitcheroo X locks up completely.

                  That's not even performance or features, that's the most basic stuff like not locking up X.

                    So.. has erroneous rendering been completely ruled out?

                      Everything looks the same to me when I watch all the tests.

                        I mixed up the the results of radeon for low screen resolution at OpenArena 0.8.8 with Catalyst's results for high resolution when I wrote my comment above. But apart from that, it looks quite good for radeon. Now, tests of more demanding games would be interesting.

                        Open Arena 0.8.5, 1920x1080:
                        3.11: 450 93%
                        3.12: 455 94%
                        Cata: 482 100%

                        Open Arena 0.8.8, 1920x1080:
                        3.11: 101 46%
                        3.12: 116 53%
                        Cata: 216 100%

                        Reaction Quake, 1920x1080:
                        3.11: 184 24%
                        3.12: 344 57%
                        Cata: 599 100%

                        Xotonic 0.7, 1920x1080, Low:
                        3.11: 317 121%
                        3.12: 343 130%
                        Cata: 263 100%

                        Xotonic 0.7, 1920x1080, High:
                        3.11: 183 97%
                        3.12: 221 118%
                        Cata: 188 100%

                        Xotonic 0.7, 1920x1080, Ultra:
                        3.11: 161 100%
                        3.12: 190 119%
                        Cata: 161 100%

                        Edit: If you sum up the FPS and devide them by Catalyst's results, you get:

                        3.11: 1396 73%
                        3.12: 1669 87%
                        Cata: 1909 100%

                          I disabled Adblock but there are animated flash banners which make the CPU fan spin quicker and make more noise so I enabled it back, without animation I'd turn adblock off for phoronix.

                            Hello.
                            I have read that AMD is finally making some progress in the OpenCL proprietary implementation to can work with Blender 3D and other similar programs. Is AMD working on improving OpenSource OpenCL implementation too?

                              Yes.

                              (Though Gallium OpenCL is behind. But it may have better compiler which is such a pain for Blender...)

                                Michael,

                                Every now and then when a change comes up which could substantially affect linux gaming performance, we need to see some current-generation games/benchmarks being used for testing. Knowing there has been some progress in benchmarking with Steam / Source engine games, perhaps such benchmarks should be seen every once in a while. And whenever it becomes too tiring to use Source engine for benchmarking, Unigine Valley would provide a pretty good alternative.
