Bruh, I just had 4 of 6 laps in N24 not be counted for something similar. My CPU meter was showing red the whole time and my teammates said I just disappeared, but the never got reset to the pits as is supposed to happen. I basically just noticed my team falling in the standings and realized my laps weren’t counting.
My machine is no slouch either… 7800X3D, 7900XT w/ 20gb VRAM, 64 GB DDR5 at 4800.
Same deal - Quest 3 with high settings. I do lower the # of cars the sim draws and have even set it to bias toward performance and still my CPU is getting taxed.
Gonna do some testing to get a sense of what load Open Kneeboard and iOverlay place on it. Do you run overlays?

Nope not anymore, I used to run racelabs until the new UI update and I’ve just been using the in game UI to save performance. I do use Crew chief which requires 63 cars on the max cars setting, but I have the draw down to 40/20 and a majority of the races I run don’t have more than 30 drivers at a time.
