• Added an optimization that will increase frame rate by up to 10% in systems using the high detail terrain.
  
  
• Added a self shadow texture size option in the "Advanced" Graphic Detail options menu. The larger you set this, the smoother your shadow will appear but it will take up more video memory. If you set it too large for your system, it will cause a hit to your performance.

• Changed the look of the low detail water and coastlines.
