Does anyone know the status of DSP/GPU acceleration on OS X? What's the minimum specs to support it (if it's supported at all)?
The new video acceleration API is only available in Mac OS X 10.6.3 or later and is limited to GPUs models such as NVIDIA GeForce 9400M, GeForce 320M or GeForce GT 330M. For more details you can look at Apple’s technote. Here is a list of the Mac models currently supported:
* MacBooks shipped after January 21st, 2009
* Mac Minis shipped after March 3rd, 2009
* MacBook Pros shipped after October 14th, 2008
* iMacs which shipped after the first quarter of 2009
(Mac Pros are not supported as of today)So... no OS X speedups yet.
