The videos are recorded in real time on an off the shelf mid-range computer. To compensate for the video’s horrible 30 fps we have the engine render each frame 8 times for smoother motion (yes, in real time). This is a feature available also in game. The computer doesn’t have fast storage (just a regular HDD) so we have to compress the video in real time which is a huge load on the system. Bottom line, it’s fast, really fast. In the videos I personally play one character and the other is AI controlled, all in real time while recording the video at effectively 240 fps.
