Hi, I know there have been various reports on these symptoms over the months but despite updating to the latest version (4.4.2.2000), the problems persists (on Win XP, dual core, 32bit, 3,500 GB RAM).
YouTube: the higher the resolution - or when in fullscreen - the more jittery the playback. The CPU will reach 100% and stay there until resolution is reduced. Even on relatively low resolution videos (360px), when there is fast movement (for example, a comedian running across a stage) the video stutters and goes out of sync with audio when in fullscreen.
Note: when I say high resolution, I don't necessarily mean within YT's settings (240/360/480 etc). I can be in 480px mode with few problems if the video is recorded in low quality but if the video is a modern, high quality recording, the CPU goes up and the problems begin. Forget 720px - not happening.
Action taken
I've tried various user agent settings, updated flash player, deselected graphics hardware acceleration, forced flash-player playback, and switched between Ultra and Retro modes, with very little, if any improvement.
Download manager: when in use, the CPU increases and the browser becomes generally slow when switching tabs. I cannot watch a video whilst downloading (unless it's low resolution).
If I watch a video in a standalone application (for example, in VLC), there is no problem.
Overall, the problems have persisted for most of this year now.
All drivers have recently been updated. No other major changes to the computer.
I hope the above description is useful and wonder if anyone can advise if Maxthon is still working on this, given up or offer a solution I have overlooked?
Many thanks.
