## Description: Removes clamping on motion blur scale to allow framerate independent motion
## blur to scale longer than realistically possible when render framerate is higher
## than target framerate.[br][br]
## [color=yellow]Warning:[/color] Turning this on would allow over-blurring of pixels, which
## produces inaccurate results, and would likely cause nausea in players over
## long exposure durations, use with caution and out of artistic intent
