The game is loading fine and i can play at least 4+ hours till the error comes up.
The error appears asap though, once i get in the garage and try to customize some specific car parts like spoilers and exhausts and not on every car, just some random ones, but always on the Buick GNX!!! Hilarious and annoying at the same time! It freezes for a few secs and then black screen followed by the error message...
I 've too tried almost everything mentioned at OP and even more from searching around the net and it still persists.
In the scrs attached you can see the different forms it manifests to me, in relation to what i try to customize and/or the gpu driver i have at that moment.
* I did clean installs of the gpu drivers every single time, but no luck there anyway.
