Lag-O-Meter

Press numpad 4 to start. SEE WORKSHOP PAGE FOR HOW TO USE
When internal bar is spinning, it spins so fast that it looks like there are many spokes. Heres how to read the meter:
6 spokes: Great
8 spokes: Framerate is changing rapidly
4 spokes: OK
2 spokes: Fair
2 wobbly spokes: Poor
2 spokes moving in steps: Bad

How it works:
The bar spins very fast. The game takes a "picture" of what is happening in the world and sends it to your graphics card, and then to your monitor. This is the framerate. If the game is lagging, the framerate decreases, sometimes too small for us to see. The lag-o-meter lets us see this. The wheel has 2 real spokes, and (assuming the framerate is great) the game takes a picture of it 3 times during one rotation, and your brain blends this together to be six spokes. When the framerate drops, the game (assuming the framerate is ok) only takes a picture twice during the revolution. This means you only see 4 spokes. When the framerate is bad, there are less than 20-ish frames per second. At 4 frames per second, your brain does not blend the pictures together, and you can clearly see the "choppiness" of the video, and it is very difficult to navigate in this state. The lag-O-meter warns you that your game is starting to lag BEFORE it is too late.
