A overlay window showing the a frame time graph with the current frame time, ~10 seconds of history as well as reference lines for the current avg. and a configurable target frame time. This is considered a debug tool to support in any efforts that are related to understanding current frame times of the games. More specifically this can be used to asses impact of any bemanitools hooking to the game’s main (render) loop.
