Sorry, but I have stuff to do IRL, and I have a lot of other games. So, yeah, I'm not really here currently, is that a problem ?
I don't think so, all members are able to answer, so even if I'm not here, it's not my fault if nobody answers your question.

@estradal : try to find the original visualsettings.dat file somewhere (or ask to a friend).
I think that you really need a clean and fresh install (talking about data files and modded cars too).
