I am experiencing random FPS drops for 5 to 10 seconds down to 20FPS in ranked mode.
In single player I have a constant 140 FPS with full details, not a single FPS drop since release of the game. My hardware is rather powerful (Geforce 4080, Intel Core Ultra 285k, 64GB). All drivers are up to date, so I doubt it is a problem with the hardware. Internet is running smooth (1gbit down, 250mbit up, fiber, 20-30 ping)
It happens almost every game in ranked mode. Everything is running fine and all of a sudden those FPS drops occur for a couple of seconds. It happens on all tracks, and every time at a different position on the track. It seems like a multiplayer problem to me. I even tuned all graphic settings down, but that didn't help either.
