1. Do not compress materials in a confined space. Ex: Using the drag tool against the walls.

2. Be passive with adding and removing things and be careful when drawing over already existing materials in the world.

3. When you first start the game it determines your graphics cards power and limits your particle limit to fit this. However in many cases including my own its best to stay a healthy amount away from the highest to prevent more frequent crashes.

4. Crashes are bound to happen regardless but trial and error will get you far into preventing them.
