In 3D races, my car sometimes activates DRS even when there’s no car visible ahead. I’ve noticed that sometimes it’s a backmarker, and other times it’s the car one position ahead of me, but the car doesn’t appear on screen.
When I click on the car that’s one position ahead, it briefly shows up in the sky and then returns to the track, becoming visible to me from that point on.
I’m using the NVIDIA GPU instead of the laptop’s integrated GPU.
