Thibault Imbert just blogged about the release of Flash Player 10.1.82.76 which includes support for H.264 GPU Decoding on the Mac.
You should notice now a nice difference when playing H.264 content on your Mac in terms of CPU usage. We rarely enable new features in security releases but we really wanted to enable such a cool feature. For more details about it, Tinic already posted about this.
Some of you may remember talk of a Flash Player “Gala” that was put out as a beta right before Flash Player 10.1 was released. The GPU decoding didn’t make it into the 10.1 release so we had to wait for a security release to add it. That security release is here and it should make quite a bit of difference for Mac users who are playing H.264 video through the Flash Player.
