"Keyboards are less than ideal when many keys are to be pressed at once, as the limited circuitry means that only a certain number of keys will register at one time. An obvious example of this is phantom key blocking. On older keyboards, due to the circuit design, sometimes pressing three keys simultaneously results in a 4th keypress being registered. Modern keyboards prevent this from happening by blocking the 3rd key in certain key combinations, but while this prevents phantom input, it also means that when two keys are depressed simultaneously, many of the other keys on the keyboard will not respond until one of the two depressed keys is lifted. Better keyboards are designed so that this happens infrequently in office programs, but it remains a problem in games even on expensive keyboards, due to wildly different and/or configurable key/command layouts in different games."
I read this on Wikipedia, and I'm pretty sure that this describes my problem. This is my biggest problem in games, and I dont understand why nobody has found a solution to these keyboard problems. Does anybody know of any way to turn the beeping off, or if there are any programs that can make it so that my keyboard can register 4+ keys at a time? If it helps anyone, I'm using a Logitech S510 wireless keyboard/mouse combo right now.
