The age old tracers debate
So long as they are useful to me as a simulator pilot I'm not going to complain too much. I hope everyone remembers that tracers look like lasers because we all saw StarWars at some point or another and StarWars is based on World War II air combat videos. Real laser beams travel at the speed of light in a continuous stream rather than defined pulses like a tracer (but unlike StarWars).
The pictures themselves look great. I think it's sometimes silly to complain about the visuals of an explosion until it's seen in motion. Often the various frames of an animation have an overall effect that cannot be seen from a single frame.
