Mankind Divided stuttering on modern specs?

Spec:

9070XT

7800X3D

32GB 6000MT Cl30

Is anyone experiencing some really terrible micro stuttering? My FPS will average 144Hz but when I stop moving and start up again, the fps will drop to 25 before getting back up.

I tried turning off exclusive full screen and fooled around with double/triple buffering, but it doesn't make that much of a difference.
