I've read a lot about havok physics but i don't see any feature that indicates if this engine have the advantage of use the gpu for the mathematic calculations.
Thanks in advice for any information about this.
The free Havok download uses CPU-provided hardware acceleration (like SIMD) but doesn't use any GPU-based hardware acceleration for its mathematic calculations. This is something you might see in future versions of Havok but right now it's all CPU-based. Happy coding :-)
