    Hi,
    I´m having FPS drops, to 50 or so from 74 I have fixed.
    It´s weird that Afterburner shows 48% CPU and 25% GPU use.
    What can be happening?

    Nordschleife or Zhuhai with time multiplier?

    Also, these numbers can be confusing because the game only uses one CPU core, so it will always be below 100%, even when the game is bottlenecked by single core performance. And then the GPU will be underused too.

    As @Maskerader said, check the individual cpu cores usage, one of them is probably maxing out and bottlenecking the fps.

    Just a note, if you are using afterburner you are probably also using rivatuner statics server? That has been known to cause issues in the past. Generally speaking make sure all other apps you do not need (browsers etc) are closed and not running in the background.

    I had this happen to me unexpectedly in the past also. Have you by chance been prompted by the sim that you have an unknown controller and attempted to assign it a profile? I’ve done this and on my system which easily runs at all settings maxed on triples, was suddenly super choppy. Turns out the sim didn’t like my adding an unknown device profile.
    Just something to consider.
