It supports OpenCL acceleration.
yes openCL is supported but just like CUDA there isn't a "one size fits all" since openCL is only supported in one feature: http://usa.autodesk.com/maya/features/
Simulate both soft and rigid bodies in a single system, with the high-performance, open source AMD Bullet Physics engine.
Create highly realistic simulations of cloth, rope, deformable objects, and ragdoll skeletons.
Take advantage of discrete and continuous 3D collision detection.
*Available on Microsoft® Windows® (64-bit only), Linux®, and Mac OS® X operating systems; OpenCL acceleration on Windows and Linux offers additional performance benefits on those platforms.
now it doesn't specify what additional performance benefits.
the benefits of openCL are great and are just now getting some attention but developers aren't changing their code overnight.
