Here's the promised 4k youtube-in-firefox tests. 4k is a bit more stuttery than normal with the patch, but not near as bad as I expected it to be. I can normally run 4k60 at 80-85% normal speed with occasional stutters but without freezing the video entirely until I drop the speed down again as I often have to do if I try running over that. With the patch I was doing 70-75%. So there's definitely some effect on 4k60. Switching to the performance cpufreq governor from my default conservative, as usual, helps a bit, but not a lot, maybe 5%, tho the frame-freezes seem to recover a bit better on performance. In addition to long video freezes at the full 4k60 100%, even normally I'll sometimes get tab-crashes depending on the video. I didn't have any for this test but then I'm so used to not being able to run at full-speed that I didn't try it for long. I can normally run 4k30 videos without much problem on default conservative. With the patch I was still getting some stuttering at 30fps on conservative, but it pretty much cleared up with on-demand. I did just have a tab-crash at 4k30, something I very rarely if ever see normally on 4k30, it normally takes 4k60 to trigger them, so it's definitely affecting it. But... other than slowing down the usable 4k fps, I'm not seeing any of judder artifacts on the work (non-video-playing) monitor that I was seeing with the high system load but relatively low video load build testing with only FHD video. That surprised me. I expected to see more of that with the more demanding video. But apparently that's tied to CPU or memory load, not video load. But nothing like the problems mnrzk's seeing with the patch, at all. Both monitors running fine in text mode, login, startx to plasma, running fine there too. Hardware cursor's fine. The only thing I'm seeing is some slowdown and judder, as described above. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
