I havn't played OMSI for a whilst (mainly cos I've been busy) but I went to play it just now and everything (apart from buildings) was transparent, I couldn't see my bus, AI buses, cars or peds.. It's driving me mad, epecially since it's hard to know where the hell you are
Bus at the bus depot which is invisible apart from the lights
Bus again at the depot, showing no other buses which should be there
Bus parked on some road, no idea where..
Stopped at traffic lights.. which are also transparent.. where the grass is, is infact a road... had to go round the corner for it to show.
Also when I try to exit the game I can't I get an error, in german... and to close my game I have open the task manager which is a really annoying way of closing it.
Never had a problem with OMSI until now (apart from the exit game error, which i've had since getting it)
Edit: One thing I must say is, if I view the bus from inside, it's all fine (well the bus is.. everything else is still transparent)
Edit 2: I've just reinstalled OMSI with the latest verison but no luck, this really sucks
