Current Bitrate: 4060kbps
With GPU acceleration: Plays smoothly, CPU 30-50%
Without GPU acceleration: Plays smoothly, CPU 70-90%
On the other hand, this youtube 1080 flash video trailer isn't smooth with or without acceleration:http://www.youtube.com/watch?v=siQgD9qOhRs
With GPU acceleration: Noticeable dropped frames, CPU 60%
Without GPU acceleration: Slight stutter, CPU 90-100%
So I did a quick check with this clip on my demo box. Results seem a little odd and probably require a deeper dive to better understand what is happening given the difference between Accel. on and off.
While I would not say it was completely stutter free, it played very good. The observable stutter was really during the scene in congress and even that was only slight. Rest of clip played very well with very little observable stutter. During the action sequences, it was hard to see any real stutter. That may be because the editing was so quick, it was not noticable. Likewise, during the slo mo scenes, it would be hard to tell what was stutter and what was slo mo.
Now, I would say a clip may not truly relate what watching a full length, 1080P movie streamed over the internet might be like. I would prefer to watch something for 15-30 mins to get a sense of how the experience might be.
However, with that said, while the clip was not perfect, it did play very good with only slight stutter during parts of the clip.
With GPU acceleration, CPU was ~55 -65%
Without GPU acceleration, CPU was ~60-70%
