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.
Give each lab its own glow: one color or a list of colors, animated as a smooth cycle, hard steps, breathing or strobe. Works alongside Disco Science: labs you set up yourself keep your colors, the rest keep the research colors.
