I upgraded my graphic card from GT 220 -> GTX 550 TI , and I don't see any improvement in fps ( maybe several frames) . That's very strange indeed, is the CPU a bottleneck than in OD code ? For large map I get 32 fps .., what is your hardware and what is your OD speed ?

I think you are right about the game being cpu than gpu limited at the moment. I know that at least the fact that we are using dynamic objects in ogre for everything means a lot of unneeded calculations, though getting around that with dynamic terrain seemed a bit complicated in ogre 1.x from what I remember. (Ogre 2.x has some functionality for this, but is not out yet.)

Another issue with our code is that the game objects are allocated and stored separately, rather than being put in a chunk of contiguous memory, which is not ideal for quick iteration.

If you don't see any improvement in fps, sooo you maybe right - it's unnecessary upgrade...
