Improve Performance in Arma 2

Fix crashes and memory issues in 32-bit games using Large Address Aware.

Why Do 32-Bit Games Crash?

32-bit technology has a limit of only 2GB of RAM usage. If a game hits that limit, it crashes immediately.

We use Large Address Aware (LAA) to tell Windows the program is safe to use up to 4GB of memory.

Why Use LAA?

Many older PC games were built before computers had large amounts of RAM. When these programs try to load too many graphics or textures, they hit their 2GB limit, run out of memory, and crash (often called a "Memory Leak" or "Out of Memory" error).
