In my case I thought it was the the nvidia driver, but I rolled back to the previous one and the problem persisted (game starts ok, but as soon I went in car to the track, the game crashed to windows...). Also, on " Checking integraty of files/Steam", always had 1 file misssing... Then i wondered that the only other thing I did differently yesterday, was change the game-select in SimHub (chose Automobilista instead of RF1-
@Martin Fiala warned NOT to use AMS select for some reason...).
So I replaced the .dll for the RF1 one, and that was it! Solved
...
So, long story short Paul, watch your
pesky Plug-in's closely
Cheers mate
