For me setting vsync to false as someone suggested elsewhere actually helped a lot to have the game running more smoothly. I can actually open i.e. the line menu again without the frame rate dropping to single digits. It still stalls every now and then, let’s say one a minute for a few seconds or after specific mouse clicks like buying a new vehicle. But this way at least it became playable again with like 200 lines and 600 vehicles now.
