I'm watching 720p60 videos on my netbook (amd brazos E-450 1.65 GHz),
which is as fast as an Athlon64 dual core.
I use "SVPtube", it runs YouTube and Vimeo videos, in Media Player Classic Home Cinema.
You don't need any special browser and it needs alot less CPU-time.
Just copy the video link address and it opens the video in your video player (MPC-HC ; Daum PotPlayer).

I reduced the fullscreen resolution in my video player, to 1280x720, which reduced the GPU load significantly (compared to 1200p on external screen).
This makes it possible to watch 720p60 videos on this slow system.

If you have alot of CPU power and like to watch all videos in your desired framerate, you can use
SmoothVideo Project (SVP). It works together with SVPtube.

Well, I just noticed that Youtube have converted all my movies to 60 FPS (the format they were recorded and uploaded in).

The bad news is that this failed on two videos, namely Wipeout and Mechwarrior 2 so they are not available in HD anymore. Anyone have any experience contacting Youtube to fix stuff like this?

Videos available in HD again. Guess Youtube fixed it 😀

I'm watching youtube videos inside Media Player Classic Home Cinema (livestream, not downloaded).
No flash bloatware. Only pure mp4 file, which is an easy task for a PC with a video accelerating GPU.

It all depends on the codec, frame size, frame rate and bitrate used, rather than the container format.

Oh and also depends on the video drivers, video card, and the usual suspects.

Just a heads up... Chromium performance with HTML5 has increased considerably... This is with the latest 64-bit build. Still a little microstuttering, but that could just be my Radeon 7700. The Youtube "Stats for nerds" shows 0fps dropped.

Opera 12.14 for WinXP is quite something. Perfectly smooth HTML5 video playback even on legacy hardware.

Interesting... I'll definitely have to experiment with this to see how they accomplish this. Firefox and Chrome do not support 2D acceleration in XP, well at least not out of the box. You can hack 2D acceleration in Chromium by hex editing a certain DLL, but only up to a certain version (And only with the 32-bit build):

I don't use it to watch videos (hell, my internet can barely handle 480p...), but I do upload in 720p60fps. From what I can see when viewing the files locally, and from the one video I tried to watch with it, 60FPS videos look freaking great.
