With next plugins we'll have a complete OpenCL implementation for REAL Studio. That'll be cool, because you can enqueue commands into a CLCommandQueueMBS. Those commands can run asynchronously in the background. OpenCL can have commands run on the graphics card as well as your local CPU. This can greatly improve image processing. And you have the code for the scripts there in REAL Studio. This means you run it like RBScript.
First implementation is for Mac OS X 10.6 and newer. In the future, we'll try to link our plugins with OpenCL implementation for other platforms.
PS: Implemented in 11.1pr5, so please test.
