To start off, my PC runs this game at 4k 100fps on max settings, but I still have two particular bugs.
If I set a free play race or multiplayer private lobby to Rain, the rain never happens. I can set the race for 10+ laps, but it won’t rain on any environment. Rain only seems to work in career.
Headlights flicker on and off for unknown reasons at night, sometimes just one headlight at a time and other times no headlights at all.
