Using the *Mesh* option in *Properties > Physics > Rigid Body > Rigid Body collisions* as the collision shape often makes the simulation unstable (objects jittering, falling through other objects, flying out of the scene, etc.)  
This still can happen even after cranking up the *Step Per Second* value in *Properties > Rigid Body World*.

What are some methods for getting stable simulations while colliding objects with holes in them that other objects need to fall through? (for example a torus)

The tips below are great, but I noticed that problems still tend to occur with collisions between to objects with *Mesh* collision shapes.

Are there any other solutions for getting decent collisions with two mesh shapes?
