The Multi-Patch replaces the GameSpy master servers and optionally forces Vsync. The GOG.com and Steam versions are already patched.

Modified LuaJIT library[edit]

Users have reported increased performance, especially in script-heavy mods.
Use replacement files[citation needed]
  1. Download the modified library.
  2. Extract the content of LuaJIT_EXPERIMENTAL_latest.zip/bin in <path-to-game>\bin.


It is recommended to backup the conflicting files before replacement.


Performance increase with the "4GB patch" on systems with at least 3GB RAM[edit]

It is a good idea to backup the executable before patching even though the 4GB Patch program makes a backup itself.
Make sure your game is fully patched before applying the 4GB Patch.
Avoid playing multiplayer with this patch enabled because it might get you banned if the server has anti-cheat protection.
