Im having an issue on identifying the orientation of the belts (mostly green atm) when FPS drop to certain lvl in a big factory areas. The lights on the side supposed to tell if it is moving forward or backward, but since there are FPS drop the lights can trick our eyes and show it actually moving to the opposite direction when it is not. This is a known issue in videos where u can see a helicopter fly up and rotor is stationary due to synchronized FPS with rotor RPM. With blue belts it may be even more scuffed.
Suggestion:
Give us an option to set the lights stationary, change the indicator from lines to arrows or something.
Or just set all belt line blinking on the same lvl as MK 1 (red) belt. The line color is enough to know how fast is that belt we looking at.
