In this minor release of Sonettic-Cinema HD flash video player we have added support of hardware (GPU) Acceleration to playing video in full-screen mode. GPU Acceleration will be switched on only if it's available on client's system.

GPU Acceleration is fully fledged compositing (+some extras) using some functionality of the graphics card. Think of it being similar to what OSX and Vista do for their desktop managers, the content of windows (in flash language that means movie clips) is still rendered using software, but the result is composited using hardware. When possible we also scale video natively in the card. More and more parts of our software rasterizer might move to the GPU over the next few Flash Player versions, this is just a start. On Windows this mode uses Direct3D, on OSX and Linux we are using OpenGL.
