Renders at 120 or 240 FPS without speeding the game up. Factorio draws at most one frame per game tick, so this mod runs the simulation at 2x or 4x ticks per second and slows every per-tick speed, duration and animation by the same factor. Belts, inserters, machines, robots, the character, vehicles, day/night, pollution and enemies keep their real-time speed. CPU cost per real second rises by the same factor.
