I've been trying to turn my single threaded project into multi threaded.
Currently all i've done is this code when i create the world (SolverMt causes a crash when i use it so i use solver instead).

Code: 

Physics::Physics() :broadphase(new btDbvtBroadphase()){collisionConfig = new btDefaultCollisionConfiguration();dispatcherMt = new btCollisionDispatcherMt(collisionConfig, 40);btConstraintSolver* solvers[BT_MAX_THREAD_COUNT];int maxThreadCount = BT_MAX_THREAD_COUNT;btConstraintSolverPoolMt* solverPool = new btConstraintSolverPoolMt(maxThreadCount);btSequentialImpulseConstraintSolverMt* solverMt = new btSequentialImpulseConstraintSolverMt();btSequentialImpulseConstraintSolver* solver = new btSequentialImpulseConstraintSolver();world = new btDiscreteDynamicsWorldMt(dispatcherMt, broadphase, solverPool, solver, collisionConfig);
I know im atleast missing a task scheduler, tried creating one with

Code: 

btSetTaskScheduler(btCreateDefaultTaskScheduler());
but performance seemed to be the same (or perhaps a bit worse).

What are the steps to implement multi threading and how do i know if it is working?
