    Phoronix: AMD Catalyst 14.4 Brings Few Linux Performance Improvements

    On Monday AMD made publicly available the release candidate to the Catalyst 14.4 Linux driver that brings full OpenGL 4.4 support. Some Phoronix readers have reported performance changes with this new driver update, so I have done some comparison tests on several AMD Radeon graphics drivers to see how the performance compares with Catalyst 14.4 on Ubuntu Linux.

    How about trying it on a more limited CPU? There could be improvements on lowering CPU overhead.

      The Unvanquished ultra settings showed improvement in peaks: 290 went from 74 to 62 for example.

      BTW it's hard to compare when the runs are spread apart. Can they be sorted so that each card is next to each other? "290 old, 290 new, 6950 old, 6950 new"

        Using an expression used in ET:QW "I don't care"

        The only thing i noticed in 14.4 was a slight smaller stuttering and that was that....then , like i said in the other thread, made yet another clean install of XUBUNTU 14.04, compile libtxc_dxtn and kernel 3.15rc2 and quite simply the OSS driver beats the c++p out of Catalyst in all performance and quality parameters that you can think of....

        Catalyst is now for me a dead horse.

          Did he mean to say "A Few"? Saying just "Few Linux Performance Improvements" sounds like bad news to me.

            How's input lag in source engine games with mediocre hardware?

              So which of these benchmarks use OGL 4.4?
              Oh that's right...none.

              Instead of concentrating on backwards compatibility AMD is focusing on the upcomming 4.4 spec because the upcomming titles are gonna be using it.
              It's a good idea. AMD should be focusing on the future to get a handle on the present. Everything will eventually work out.
              As GPU's get more powerfull further refinements in older spec's become increasingly irrelevant.

                We have a winner. Another series of useless benchmarks.

                  Not at all, Unigine Heaven and Valley are great benchmarks, as we can see in the tests. I don't know of any games that are using OpenGL 4.4 yet, or even games that are fully using OpenGL 4.0. The only one I know of is Christophe Riccio's (gtruc) OpenGL Sample Pack, and that's not a benchmark, more of a "test what the drivers can do and how they conform to the specification".

                    Could You look into this:
                    Those are fairly nice test cases. No FPS for those, ofc. But general score should also be nice (and as anyone can see nobody can perfect score yet.)
                    Gtruc is actively maintaining them, and updating every time new OpenGL come along.

                      Still here with this 14.4 RC driver. I tested the Half Life 2 on (low level) HD5450 and Athlon II x2 250, 4GiB RAM, Fedora 19 64bit, Gnome Shell 3.8 and 1280x1024 desktop resolution, and "input lag" is in place. In game, if I do mouse movement, game does nothing and after 200 - 700ms redraws the scene acording to my mouse movement. I have tried with direct mouse input, with filtered/unfiltered input and with mix of mouse acceleration and sensitivity values and lag is persist. But this is not only mouse lag, with use of keyboard in HL2 i have same experience. On Windows 7 with catalyst 13.12 runs HL 2 without this input lag.

                      Same is for Catalyst 13.12. With Mesa 9.2.4 OSS drivers HL2 runs with less FPS but without this terrible lag. On my second low end card (GeForce 210) with NVidia driver 334.21 runs HL2 relatively smoothly, without input lag and about 60 FPS.

                        That sounds very serious. Any chance we can get a comment from the ATI devs? Have you reported the bug on their website?

                          No, I don't have reported this bug to AMD. This is "most common" bug for Linux Catalyst driver suite, as I see on Google, Ubuntu forums, Steam communities and other internet places. In HL2 may help set gl_finish variable to 1 in game console (https://github.com/ValveSoftware/Sou...mes/issues/431). Some other people advices to turn off tear free desktop feature in CCC, but I don't have much time to try install,uninstall and testing all posibilities with linux Catalyst drivers, so I am staying on Mesa OSS drivers which are (IMHO) best option for running AMD GFX HW on Linux systems. Catalyst driver suite for linux is crappy software. For Nvidia hardware on Linux systems, the situation is completely reversed. They have relatively good proprietary drivers, but Nouveau driver is not so good for daily usage.

                            Thanks! I've stopped bothering to install the Catalyst betas since they can't manage to fix this dreaded input lag. I've never seen such an ENORMOUS bug go unfixed for so long and affect so many titles. Really, it's pretty damn hard to believe! I'm using the latest Mesa from git and kernel 3.14.1 and performance is very good in Source engine titles--hell, it's good across the board!

                              Potential Performance Improvements Found

                              Michael et. al. -

                              I performed benchmarks on my system running the A10-6800K Richland 4.1 GHz APU and noticed some potentially (very) significant performance improvements. As I note in the post, my environment is somewhat uncontrolled, but the high-end consumer APUs seem worthy of further investigation.
