What kind of optimisations have you made? e.g. are you using something like frustum culling?
- Fully featured frustrum culling (Actually already built into Ogre3D)
- Chunk devision of vullen data
- Fog
- All in one colorpallette optimization (every block actually displays a different part of the same image)
- Inteligent chunk refresh
- Unseen face hiding (Sides of the world are also hidden)
- Memory Optimization (One array holds every block and it's color)
- Special water rendering
- Some other stuff I forgot
