Every time the car gets closer to the camera, shadows on the car morph into view. Look at the interior and seating area to get an idea of what the issue is. Happens on every car. Been an issue since day one.
Like that since the first Forza game. Never going to be “fixed”. All racing games have this optimization. Some more (Forza, iRacing) than others (GT7).
Well, that’s a stinkapoo. I have noticed it in others but thought this is a “new gen Forza” we wouldn’t have to deal with it. Kinda ruins replays. Kinda.
