HTML5 and hardware acceleration

[Haleth]

Hi!

Simple question but I've not been able to find the answer to this. Is it possible to disable hardware acceleration for HTML5-based video content? I much prefer it to Flash because not having Flash installed makes browsing a lot faster. However I often play YouTube music in the background when multitasking and I find especially with WoW that it puts a lot of stress on the graphics card. Flash has an option to disable hardware acceleration so it doesn't have that problem.

I know I could just install Flash and use a plugin that blocks it on all sites apart from YouTube but that's not the most elegant solution to be honest.

Any ideas?
