I modified my application, so doom runs on the 9 numbers of the numpad. The frame rate is about the same. If you haven't yet, you can watch the original (single key) version here: youtube.com/watch?v=q7b9glYuAXw

If you wonder, why you can see the numbers, it's because these are OLED displays and the numbers have "burnt in" over the years.
