Console game performance has always been an area that we've been interested in here at PC Perspective but has been mostly out of our reach to evaluate with any kind of scientific tilt. Our Frame Rating methodology for PC-based game analysis relies on having an overlay application during screen capture which is later analyzed by a series of scripts. Obviously, we can not take this approach with consoles as we cannot install our own code on the consoles to run that overlay.
Recently, we came across an open source project which aims to address this. Trdrop is an open source software built upon OpenCV, a stalwart library in the world of computer vision. Using OpenCV, trdrop can analyze the frames of ordinary gameplay (without an overlay), detecting if there are differences between two frames, looking for dropped frames and tears to come up with a real-time frame rate.
