--- Comment #15 from Duncan <1i5t5.dun...@cox.net> --- BTW, whatever optimizations you've done to kwin_wayland since the a07 commit above, have had a *BIG* positive effect. While my decade-old AMD bulldozer-1 fx6100 (2011) with half-decade-old (2016) Radeon rx460 graphics could (with some stress) do 4k60 in vlc, in firefox on youtube not so much -- I could get 4k50 with some stuttering, but @4k60, the image would freeze on many videos and often not come back until I hit pause momentarily to let it resync. With the recent optimizations I'm now doing 4k60 with some stuttering, same firefox, about the same stuttering as 4k50 before, so on my system the optimizations have been good for ~20%! FWIW this is the video I've been using for testing, a 5 minute 4k60 Costa Rica nature video: https://youtu.be/LXb3EKWsInQ Again, while I still get some stutter, for the first time I could play it clear through without having to pause the video to resync -- it will still freeze occasionally now but much less and now it always comes back without me having to touch pause, where before it'd stay frozen until I paused to resync, and it'd do that repeatedly, making it effectively unplayable at the full 4k resolution unless I slowed it down. So it's a BIG difference! =:^) -- You are receiving this mail because: You are watching all bug changes.
