Windows 7: YouTube lags (100% CPU) in 720p/1080p with Chrome only

Windows 8.1 Pro with Media Center
YouTube lags (100% CPU) in 720p/1080p with Chrome only

From self-solving my previous post I made on this forum, I've come across one more issue that I need to solve which I can't seem to figure out myself. Other people have managed to fix this who have the same media PC as I do.

In any browser, 720p/1080p video in Flash or HTML5 on YouTube seems to choke the CPU at a constant 100% CPU. However, on IE, whilst the CPU is at 100% the video appears to playback without any issues.

Whilst this isn't so much a problem - I'm not really a fan of IE, so I would much rather have it working the same way on Chrome. Flash is up-to-date and I've disabled Chrome's 'pep' Flash to no avail.

Any help appreciated!

Sounds like something is causing your browsers to choke like that. I would try uninstalling flash and then reinstalling the latest version and see if that does anything for ya. post back if it doesnt.

Welcome to Seven Forums . When playing a HD video, open Chrome's Task Manager (SHIFT +ESC) and confirm which process is using the CPU. I'd suspect Shockwave Flash (although you mention watching HTML5 has the same effect).

You can try enabling/disabling hardware acceleration and see if any effect

Enable or Disable Hardware Acceleration in Google Chrome

You can also do the same for Flash settings

Open a video on Youtube> Right click on the video> Settings> Uncheck Enable hardware acceleration
