My FPS drops by about 10 whenever I activate the mirrors. No matter what I put in the "Min. Obj. Size" option or what texture size I select for the mirrors, the FPS drops by exactly that same amount!!! I'm even playing with Min. Obj. Size set to 0% and the texture size set to 4096 MB since the FPS will drop by 10 anyways!
Has someone experienced something like this? What could be the cause? In the Grundorf map, I get 60 FPS and when looking at the mirros, the FPS drops to 50. So that is acceptable. But in more complex maps it goes from 30 to 20 FPS ,which is annoying...
Or, and one more thing: the FPS increases by about 10 (in Grundorf map) or by 5 (in Berlin map) whenever I press any mouse button. As soon as I release the button, it drops back down.

(I can run other games at 1080p with graphs set to "ultra" and 50 FPS; I'm aware, however, of the issues OMSI has when it comes to performance. Ah, and also, I have the 4 GB patch.)
