I just updated my patch to 114800. I haven't played trainz in weeks, now when I open certain routes in surveyor mode it runs perfect even in areas with the highest scenery, but when I go in driver mode it lags super bad even in areas with no scenery detail. My computer has 38.3 GB space left because I did some cleaning and I have the right graphics card on my PC, so I'm confused on why this is happening, any help or suggestions please?
