The game's ''bitness'' affects how much memory it can use: ≈3GB in the normal 32-bit mode, and unlimited in 64-bit mode. 32-bit is fine for most players, but those with a large number of mods (or large mods) can experience <tt>OutOfMemoryException</tt> crashes. Changing the game to 64-bit unlocks access to all available memory to avoid that (if the computer itself has enough memory available).

The game's ''bitness'' affects how much memory it can use. Since the game is normally 32-bit, it shares the first ≈3GB of memory with every 32-bit app on your computer. In 64-bit memory, it has unlimited access to your computer's memory.
