I guess the ultimate point of these snippets is to keep the physics timestep fixed while graphics run at higher fps interpolating frame results. There are obviously
better solutions than this piece of code and those will be more relevant at later development stages... Since your graphics run at constant 30fps, you could perhaps replace that code with just simulate(1.0f/30.0f) and fetchResults(true) and keep looking until you find the actual problem. fetchResults can be called right after simulate as long as that first parameter remains true. I suppose it's also possible to "hack" some speed by making that dt > 1/30 (or even better call twice those functions), did you try the direct approach?
