Nvidia PhysX

I was not fully aware; thanks for the link. However, I am mostly interested in hardware acceleration (GPU/PPU). Does the software-only PhysX API provide mutli-threading capability? How much parallelism can you achieve without GPU acceleration using PhysX?

Yes, PhysX does provide multi-threading, but given the nature of CPUs with their limited cores, it cannot offer the same parallelism that a GPU can.

Maybe Nvidia ports it to OpenCL some day to not let it die... :sneaky:

As far as porting goes, probably not OpenCL but DirectCompute seems like a possibility in light of this:

PhysXInfo.com: Is FLEX purely GPU accelerated library, or will it support CPU execution? Is it plausible to see FLEX ported to OpenCL or DirectCompute?

Miles Macklin: Right now we have a CUDA implementation and a DirectCompute implementation is planned.
