When I activate the performance-meter in the settings I can see my FPS in the top left corner.
When the game runs smoothly, I have one dot next to the fps, like that: "FPS: 70." However, in bigger fights I get some input latency (I can feel the delay between moving my mouse and the screen moving, which is very annoying and confusing). The bigger the latency gets the more dots I get next to the FPS, up to 3: "FPS: 70..."
What exactly do these dots mean?
