    Phoronix: Catalyst 14.3 Beta Linux Driver Fixes OpenGL Performance Issues

    AMD has released a new Windows and Linux Catalyst proprietary graphics driver. The Catalyst 14.3 Beta for Linux doesn't advertise any new features, but it comes with some bug-fixes...

    Too early for much improvements.

    AMD is busy with Mantle, and Steamboxes are not here yet. (So if AMD have to prioritize...)
    EDIT:
    Radeon drivers are not yet ready for prime time for such perf. oriented audience as Steambox users. But hey, maybe it will change with radeonsi gen hw.

      I'm tired of catalyst and don't really want to try it out.
      My system runs much smoother with RadeonSI. Everything that works just works without issues, crashes, glitches.
      Metro runs very well on Kaveri (mesa 10.2 git)

        The performance improvements for Nexuiz are interesting, would be interesting to see what actually happened (benchmarks of Quake3-ish games maybe?).

        However, it should be noted that this driver is unfortunately still based on the 13.35 branch. So the feature work from the past 2-3 months is still yet to feature in the AMD Catalyst.

          How about improving the performance for games that people actually play?

            Agreed. I fired up Portal 2 last night on my 7850 using the radeonsi driver and played for ~2 hours. At no point was the framerate anything but smooth. I don't have actual numbers, but the point is that it performed well enough that I didn't care. This is a huge improvement from when I first ran TF2 on my 6850 about a year ago. There was lots of stuttering and pausing all over the place. Of course the 6850 has also smoothed out over time, which just makes me want to thank the 3D driver devs even more.

              The poor 2d performance continue

                I have some hope that AMD will announce something for their Linux users at the GDC. Hence they invited Phoronix there.

                If not, I think that I'll run buy a high-end NVIDIA card and be done with all the torturing.

                    In all fairness, the Catalyst problems are not only with LINUX...example:

                    Enemy Territory: QUAKE Wars


                    In Windows XP i get with certain settings 150-200 FPS....and overall feeling is very smooth.

                    In W7/W8/W8.1 i get with same settings....30-50 FPS...and stutters like crazy when straffing.

                    All this with same hardware and same game settings....

                    This means that even in Window$-land, i have to use WinXP to have some decent gaming experience with OGL games...or at least with some titles.



                    Tonight i gonna give a shot with OSS Radeon to see if i can have finally some quality gaming with AMD hardware in LINUX.

                    BTW, nowadays its a piece of cake to install Steam client in SLACKWARE so i guess i will dump Linux Mint or any UBUNTU derivated for good....this is because between UBUNTU-derivated and SLACKWARE, performance of SLACKWARE is ALWAYS superior.

                    Only needed to use deb2tgz to convert steam_latest.deb to a .tgz file and use installpkg as usual to install Steam client

                      I'm waiting for the next LTS version of xubuntu and then will try out a freshly baked radeonsi for my 7870.
                      With fglrx I can run portal2, but get terrible frame stuttering. Small OpenGL games run fine as long as they are not to demanding. Sauerbraten for example is already "to demanding" and the 60-200 fps I can get, feel more like ~30-40 fps because of stuttering.

                      Btw. does anybody know if the oss driver supports dynamic vsync(GLX_EXT_swap_control_tear)? The closed drivers only support dynamic vsync on windows.

                        Not really. It's same Linux kernel, graphics drivers, source code and compiler with slightly different flags. Also don't expect source based distributions to give you more than 10% speed up after heavy tuning for your hardware. It's all about customization ability.

                          For several times, i compiled same kernel (from kernel.org) with same settings for both, running in same hardware and UBUNTU and derivates felt laggy in comparison to SLACKWARE...
                          This was tested with native games like ET:QW and W:ET that are games i play since 2007 till today in all OS....

                          This is ongoing for several years now , always with same results.

                          I also tested same situation with different rigs....same result over and over.

                            Congrats, you just proved the placebo effect.

                              What placebo effect ?!?

                              Besides LESS FPS , when i press a mouse or keyboard button the response was and still is clearly slower to the point is noticeable as opposite to SLACKWARE where it fells instantaneous.
                              It was and continues to be so bad that i almost couldn't kill anyone in online matches no matter the settings.
