Threading and OpenCL Bullet

[mspong]

My engine runs the physics in a separate thread than the OpenGL rendering. Should I reconsider this in light of the coming OpenCL support for Bullet? Will there be issues caused by trying to use the GPU from multiple threads simultaneously?

[Erwin Coumans]

Good point. We are still doing R&D on the OpenCL work, but we need to make sure that synchronization is provided in case graphics and physics run in separate threads.
Of course you need some spare GPU cycles for OpenCL, unless you want to run OpenCL on the CPU.

Thanks,
