I have this problem where it seems to have a kind of a "white layer" over the car in the showroom mode. I remember having this issue a long time ago but I can't remember how I solved it. I've tried validating game files through Steam options. I've tried deleting all of my custom liveries. Thing is this bug affects every car, every livery, no matter if it's a custom or original livery. The only thing I didn't do was reinstalling the game, since this is only a minor bug and don't have any impact on the textures while racing. Here are some screenshots: 1. Car in the lobby: 2. Car in "showroom" mode: 3. Car on track: If anyone knows how to solve this problem without having to reinstall the entire game, please let me know.
As far I remember it’s graphic setting related. Try texture res, environment, reflection or msaa on high, not medium. The fix should be just one of those, not a combination, so not much to play with and test. I just forgot which one causes this white in showroom. (Restart the game after each change and check if sorted)
