Comments Video loads quickly and plays at the correct rate, but refreshes in dirty rectangles and is not at all watch able.
Low resolution video play back is fine with very few stutters. Struggles on higher resolution video, stutters a lot.
All video playback is excellent and smooth. Stutters are very rare.
