I had already updated wrapper to v 2.02 and had finished with blocks.. now i'm going to add car physic and release Newton Wrapper v.20

What about timestep - i still have one idea about it... anyway, if you'll create a plugin, that would be able to work in different thread and call NewtonUpdate, you're wellcome...
but i still dont understand, where this problem comes: at my comp and notebook the original version of calling NewtonUpdate() once per frame works fine, but in your example ball moves really laggy
