Thanks for your tips, I'm fairly sure that the 30FPS limit I'm getting is due to the rendering not being optimized. I've tried turning off the network thread and the logic thread with the same results. This is my first game using OpenGL, thanks for the info about sorting the objects before rendering. This will be the easiest to implement.
I'll definitely keep your suggestion of using a texture atlas, although at the moment I have so many other things to work on that I don't want to waste time over-optimizing it. > By the way, another optimization that I have already implemented is to > bake all the static objects in a single image.

What do you think? > Hmm, I'm not sure if that'll work for me. I've heard that rendering large bitmaps/textures with OpenGL can also hurt performance. So you have to break those large textures into small ones. I'd have to find a nice medium. Not really necessary in my case. But thanks though, if I ever want to improve the framerate I'll keep your suggestions in mind. Good luck with your game! > I have seen your map editor in HTML/JS, it is pretty awesome.
