Multi-thread issue: slow and not identical to single thread

Post by cuckon »

Hi all, I try to use the bullet's multi-thread method to speed up my simulation. However I encounter 2 problems:
1. The performance is slower even than when I am not using multi-threads. I have checked the windows' task manager and all the CPU is running, but the performance is strange.
(My CPU is Intel i7, does this feature have some requirement on CPU platform?)

2. The simulation result differ from non-multithread, which makes me headache. Did I miss something?

it seem like the multithreaded version is not maintained very often and i think it's even been removed in the last version
