Xorg.0.log http://filebin.ca/21306lWrU1vK/Xorg.0.log (bugzilla attachment upload does not work with lynx) portal2 is mini-hanging a lot then hangs for good ok, got git versions from linux agd5f (4.1fixes branch), llvm, mesa, xserver, and ati xorg driver. While playing dota2: many artefacts/glitches randomly appearing on the screen and choppy action (unplayable) http://filebin.ca/21BJIEUOGDQt/dmesg http://filebin.ca/21BJUPQs30LP/Xorg.0.log now with full asm and tls... same thing: choppy action (unplayable) and quite a lot artefacts/glitches on screen. Can you attach a screenshot showing the artifacts? What does "mini-hang" mean? P.S. Please attach files here directly. If your browser can't do that, please find one that can.

mini-hangs, choppy action: while playing, the game freezes briefly, and this happens randomly all the time. When there is a lot of things happening on the screen, for instance in a team fight, it freezes longer and more often (very choppy). linux drm-fixes-4.1, xserver, xorg ati drv, drm, llvm and mesa, all from git as of today, still the same issues. Ok, I nailed down the choppyness: source engine games do compile a lot of shaders live... then a "safe" llvm won't do and will cripple performance. You must maximize shader compilation performance with threading and aggressive compilation options for llvm. Vulkan spir-v will be more than welcome. One down. One to go. Those graphical glitches are also into portal2, but less visible and more rare. Got lucky and nailed the second one (for 99.99% of the glitches): R600_DEBUG='switch_on_eop' fixed 99.99% of the glitches in dota2/portal2. I open a more specific bug. |
