1. Download and install nGlide http://www.zeus-software.com/downloads/nglide 2. Extract these patched files into the montezuma folder: http://www.zeus-software.com/files/nglide/montezuma_patch.zip 3. Use vsync. nGlide should have that turned on by default but I recommend setting it on from your video card's drivers, as well as maximum pre-rendered frames to 1 for minimum input lag. 4. Launch the game using gwmonte.exe
