(have tried to ask on PCars forum...without success) i was just wondering, on PS4 in Visual FX (setting) is there anywhere an explanation what the various ON & OFFS do? the various subtle, full and etc options do? i have searched in the digital manual found nothing and also nothing in forums. also when u change settings generally, is there a button or way to reset to default settings? (this would apply to menu options and menus in the game) thanks all!
