Some knots and bolts need refitting as the PhysX 3.1 engine is a totally new API (Application Programming Interface, just so you know).
This upgrade should result in a more stable game-experience, but it also makes our server Linux deployment easier as 3.1 is already compiled for Linux.
And as an extra bonus – PhysX 3.1 also doesn’t require that you install it separately, but it can be installed as a part of the game installation, which makes it a better match for browser-based distribution.
