Randomly low/high fps

[xx_SuperRacer_XX]

This happens primarily on spa and nurburgring. But fps randomly drops and stays until it randomly goes back up. From 115fps avg to 45 fps avg. On spa this is near the pits but on the nurburgring its on the whole track. Temps are fine and drivers are updated

Check your RAM use - system and video ram. If that's being exhausted when returning to the pits, and isn't caused by a third-party plugin or tool, try lowering circuit/opponent/texture detail.
