If performance is the issue: would it be impossible or too hard to put slider in preferences? Those with not-so-good computers could choose say 10% and those with high-end computers could choose 100%. 10% would mean that game tries to give number of passengers that are 10% of maximum capasity of the bus. With good computers this would mean that in some cases the bus is full and no more passengers could be taken. In other words sometimes passengers need to wait for the next bus.
Exactly, We know this. TML has to implement the same.
Hope TML listens to the same
