strange random lagging problem

  • Hy guys,


    the problem is that for half a year the phenomenon that occurs in the game is that a random locomotive (or emu dmu ...) that worked well until then, while driving constantly fluctuates beetwen 15-20 the FPS. The result is strong lag.

    If I delete the train from the assets folder and reinstall it, it will work afterwards. I do not understand. this also happens with free and paid DLC.

    Important, I’ve been playing for years, the computer wasn’t reinstalled, I didn’t buy a new computer, the game wasn’t reinstalled either, every train worked before.


    What causes this? from many assets, possibly different?


    Thank you in advance for your help.



    Thanks
