    Phoronix: RadeonSI Starts Beating Catalyst In Some Linux Tests

    While the AMD Hawaii open-source is broken, at least for older "GCN" era graphics cards supported by the RadeonSI Gallium3D driver the performance is starting to match -- or even exceed -- the proprietary Catalyst Linux graphics driver...

    [...]and also the R600 Gallium3D driver that supports the HD 2000 through HD 6000 series graphics cards and that driver is already in a mature state[...]

    What is that suppose to mean? Is that all the performance than can be obtained for the r600 driver? I hope not, because it is still far away compared to catalyst in windows, where for example, TF2 works great, but in linux with the r600 + hiperz is still not a fluent experience.
    But the improvements done so far have been great, Im not arguing that.

        Xonotic with radeonsi driver was near Catalyst even before that so current code .

        But that is not whole true because Catalyst 14.4 has a bugs in simple tasks like that, so it struggle in some Quake3 engines games like in RTCW Forest i spotted:

        If someone have RTCW just run Forest map, it is slugish like hell there with Catalyst .

          Its good to see than its getting a lot better, the devs seems to be busy with it
          The question isn't meant it in that way, but your point is valid.

            Very nice! Does anybody have a pointer on how to use Keith Packard's glamor server with the ati/radeonsi DDX? I'm still on the glamor-egl lib.

                Hmmm, pts/et does not show that bug . 80% Catalyts performance, but radeon also have corruption when loading that ET benchmark .

                You basically needed to compile everything . Protos, xserver then drm, ddx and llvm and mesa... and . But basics are described here:

                    With my Radeon 6370M the frame rate was higher on open source then catalyst 14.4. I ran Portal 2 and Portal and the frame rate was tolerable with Open Source. In Wine the frame rat was also higher. The frame rate is also smoother on open source. Catalyst is unplayable with frame rates jumping up and down.

                    Despite how good the open source drivers are, they're still nowhere near as good as Windows. HyberZ should be enabled by default, as it works just fine for me. My other laptop with a Nvidia 9600M Gt handles these games with no problems. Drivers need a lot of tweaks.

                      I'm sorry but radeonsi beats Catalyst even with Steam games

                        Even in 3.13 the RadeonSI driver is pretty solid. Dota 2 is really the last game that I "need" Catalyst to play properly (framerate goes from about 60 to 6 without it), though the Wargames series also seems to have a few visual glitches when running without Catalyst too.

                        Cata Betas also introduce some bugs elsewhere though, like the March version inexplicably made Skpye unusable, and the April version inexplicably fixed it. I'll be glad when I can safely just stick with the open source driver without having to sacrifice any games.

                          ... In our most recent tests we have found the RadeonSI Gallium3D driver on HD 7000/8000 series GPUs to do well against Catalyst, but generally the Catalyst driver still reigns superior -- especially if considering its OpenGL 4.x support and much better working OpenCL compute support. ...
                          I'm not a gamer, too bad OpenCL isn't well supported yet.

                            Well Opencl isn't well supported on catalyst too, hopefully when Opencl comes to the Foss driver it'll work without inlining everything.

                              Does RadeonSI shut the fan up while at idle now? This is literally the only reason I still use Catalyst on Arch - the computer is whisper-quiet at the desktop, but with the open driver the fan speed is unchanged from its boot speed and the whirring noise drives me crazy when I'm trying to work.
