I've had encountered several problems since downloading OMSI with running it on a 64bit Vista OS. I changed to XP had a lot of issue with that, Vista is just a bugger to delete, but with some external help, simply deleting windows got rid of vista and i could do a quick format etc and install XP.
Now! It runs properly, set the frames to 50 and the highest frames i get even during rush hour in spandau is 26FPS, i've never had much lower than that except around U Rauthaus Spandau (on approach from Moritzor, sorry if spelt wrong) The dynamics of the AI is superb although i've had the issues of AI cars slamming into me while at a bus stop, resulting in passengers departing the bus!
I've also noticed that the AI when you're right behind one on the same schedule, they will proceed to the next stop rather than stop and pick up passengers. However it was real fun to zoom past another 92 in front me and steal back my passengers (long as none of my passengers rang the bell)
It's fantastic, the route is the perfect length, you actually feel like you need a 10 minute break after driving around. Without a 900degree steering wheel its working well for me, i don't have to over crank the wheel as the force feedback on a Thrustmaster RGT with 270 angle works better! as the game works out the steering.
Now, the night route is just awesome, its better to use a D92 at night, just because the engine is quieter (ish) but the 92 N thanks to Thiago i cant wait to drive.
There are bugs, but you know what overall its absolutely fantastic. the Fahr and Umlaufplan is excellent!
Im sure there will be more routes from the M-R duo in due course!
