High fps but not smooth. Laggy/stutter

I have the same issue since release basically. This is the only game on my PC that feels stuttery/laggy when looking around with the mouse.

My PC is a Ryzen 2700X, RTX 2080, 32 GB RAM, game is installed on a nvme SSD, 400 MBit/s cable connection and ~18ms ping to the Frankfurt servers. Playing on a 144hz monitor. I tried every settings combination imaginable, vsync/gsync on/off, lowest graphic settings, custom settings.ini etc. I get over 144 fps most of the time, only in the dropship or from really high ground the fps drops to ~110. But even when standing in a small room where the fps meter shows 300+ fps, doing a 360° is SO super stuttery, and not fluent at all. This is the only game where I experience this kind of lag/stutter, other games I played recently that run super smooth are: Warzone, Overwatch, even PUBG runs way smoother than Apex.

I've been looking for a solution since release, but so far nothing helps. I'm glad at least I'm not the only one with this problem. Lets hope there is a fix for this.
