it would be more realistic if it is busier on the railways with other train traffic. More frequent priority for other train traffic. More situations to take into account.
I agree but I feel that performance would drop further if we see much more than what we’d already have. I know a few times while on Long Island Railroad at Jamaica Station I’ve been pulling away as a coup ore grains have been arriving and you can see the effect it has.
I've had 7 M7's - 4 static 3 running - at Jamaica station with a little bit of stutter. Personally I feel this is a good trade off for a bit if immersion now and again. Jamaica is a big station too. Seems like DTG are getting better optimisation with each DLC.
