HD at YouTube slow!

[Demon Cleaner]

Whenever I want to watch any movie on YouTube in HD, it has huge slowdowns. Is this sooo hardware hungry? I have a Radeon X800 Pro GPU.

Hmm... I'm not sure about that. I would have thought an X800 would have been enough as it does contain some hardware acceleration support for HD video playback.

I'm sure I used to run HD content from youtube on my nVidia 7800GT. When I get time I will boot up my emulation system that is now using that card and run a HD youtube video and let you know how it manages.

Are you sure it wasn't your connection being slow and causing the video to slowdown? Even fast connects can suffer at peek times.

Don't think so, as there were no downloads or torrents started, I paused them. Normal videos run fine.

I noticed that sometimes too. I though it was buggy flashplayer/browser related. Sometimes my pc slows down on normal vids too when It's been on too long (> two days) and starts using the page file (even though I turned it off). a reboot fixes my problem.

It has something to do with flash. Flash has never been that great for streaming video on high resolutions (I've worked with these problems since flash MX)

Flash, my number one internet enermy now that popups are mostly blocked in browsers. Remember my rant on here a few years back about it eating CPU cyles and causing global warming? Making laptop fans screem? All for a few animated adds?

Honestly, flash misused is a plague. It's just so inefficient and a huge CPU hog. Flashblock is one of my fav Firefox addons and makes an old PC able to cruise the web at lightening speed! Without it, an old PC on the net is like crawling through mud thanks to flash.

HD content is very CPU intensive due to the high compression, with Flash it's even worse. I don't know your CPU specs Demon Cleaner, but it sounds like it's running completely off your CPU. I think all flash runs mainly off the CPU, with the hardware accelerate option on your vid card meaning simple stuff like scaling - I don't think it uses DXVA.

Take a look at task manager while watching a vid. See if your CPU is pegged at 100%.
