As you know, Adobe has been testing H.264 GPU-decoding under Mac OS X for a long time. And today, Flash Player 10.1.82.76 was solemnly announced , where this feature is finally activated. It requires Mac OS X version 10.6.3, as well as an nVidia GeForce 9400M, GeForce 320M or GeForce GT 330M video card.
Following on to the Apple blog post we are reporting a few technical details. Unfortunately, there are some limitations. Video clips with a frame width of 864 (for example, 864 × 480, which is often used in the 480p mode on YouTube) cannot be accelerated on the nVidia GeForce 9400M, this is a known problem with the GeForce 9400M for MacOS drivers. If such a video card is installed in the "Mac", then it is recommended to watch Youtube in the resolution of 720p or more. In addition, hardware acceleration is forcibly disabled on video clips smaller than 480 × 320. The first testers who updated Flash Player often say that they do not notice any difference in the processor load. In general, they did a good job, but not to the end.
