Back on topic: The autofire is set to click the mouse button every 30 milliseconds. That's about 33 times a second and is 2000 times a minute. I believe guns like the FAL max out at 400 RPM? Is this really necessary? I believe I have overloaded the keyboard/mouse input buffer and created a Blue Screen of Death on a few old Windows 2k computers at my old high school many years ago, are you sure this won't do the same? Then again, I think I set mine to about 6000 words a minute.
