Real-Time Physics Simulation Forum

Hi,
Is there a way to have the stepSimulation function to use all the cores of my CPU or even my GPU ?
Currently it is using just one core.
Thanks.

Yes and no, lunkhound has a nice multithreaded application of bullet at https://github.com/lunkhound/bullet3 , but there are limitations (doesn't scale well if you have few islands).

If you need more than that, check out the openCL Bullet3 work at the main github page, it also has some limitations though, so plan accordingly
