Bit of a wired one here. I've picked the Mclaren 720S at Imola on a clear day. When I set the start time at 06:00 with 2x multiplier with either a single track full race or practice, I get a solid 90fps in VR. But when I simply leave everything the same but change the start time to 05:00 my FPS shoots down to 30fps and GPU (2080ti) between 95-99%. Any ideas?
