If you look in the archives for the basic 3d framework code (using rendertweening) you'll find that it runs the logic at whatever rate you specify (default is 50fps I think) and the rendering occurs as fast as the machine can cope with.
I've tested it with 2 machines linked up, both running my stunt race game, and the slower machine can only manage to render at 30fps while the faster one manages to render at 60fps, but they both manage to remain in-sync and running the logic in the same manner.
