Threads will be harder to program, so why do u use threads ? who cares if its slow. At least it works.



GeometryBatchFactory.optimize(node); will make your code 40000% faster. but you can use it only on objects that dont move / change.

i dont use threads , i use AbstractAppState class like threads:|

You should not be calling rootnode.updateGeometricState().

Just attach the player’s spatial to the root node (on the openGL thread, refer to the link I posted). Then any of its controls will get updated in the update loop and the player will render.
