i found out a funny idea myself after changing my CPU from 5600x to 9800x3d, so called "stuttering" problems improved a lot. like, over >1s of "beeep" moment changed into <0.5s of "bip". and this is in my acceptable range but still, stutterings of initial drive after installation of routes and update of graphic driver remains. (as far as what i have learned from this forum) so i was driving Frankfurt to Fulda as RE50, and i quickly realized that this is my initial drive of this line after updating GPU driver. tons of shader gathering moments. so i quit playing and thinking of drive this line with ICE3 first. then this idea came up. no speed limit, no AI train, no red signal, 300kph with, such as TGV-driving mode only for shader gathering. no need to suffer from 160kph speed limits and one and a half hour of initial drive. then, like, "ok only enduring 30 mins then i can play this route without any problems" half nonsense, half seriousness contained on this thread.
I think you could do this already in-game by spawning in free roam, spawning a train, and pathing from one side of the map to the other? I might be wrong but I think free roam has no AI as opposed to spawning on foot in a timetable.
yes, you can btw, that's how I like to play TSW because for me, what really matters in TSW is the train itself, the route is just a means of using it
