Horrendous FPS performance

In the past few months, the performance of the game has gotten increasingly worse.
I have a 3080FE and a 3900X, and on medium settings i regularly get FPS drops down to between 90-140 FPS, which in this game just feels terrible and not smooth. Its like the game says i have a full 140FPS but only actually draws every second frame.

I have tried every step on this ( Blizzard Support - Overwatch 2 Performance (FPS) Issues ) guide, and after resetting the ingame settings, its even worse. Game says i have a solid 300FPS, but it feels like stuttery 30, with extreme screen tearing happening.
