I'm no programmer, but afaik it works by intercepting the games directx output using its own d3d8.dll library (you see it in the patch, and its copied to the game folder meaning the game uses that lib before any other one). This probably means that other apps working by hooks to that lib can get broken. Just my guesses though.
