Hi,
I have the exact same issue.
I'm running a i5-7600k , 16 gigs of RAM in dual Channel, and a GeForce 1080ti.
I had no issues on my 1070 and as soon as I upgraded to 1080ti I started getting the same stuttering and jumps as you. And they are totally illogical as you said. In a massive fight you'll get no issues and in an empty hut you'll get little freezes... Makes no sense.
And all this despite a steady 125fps cap which I use RTSS for (I get a good 144 if I want to but I figured 125 was the steadiest on my rig).
I tried literally everything:
-Newest Nvidia drivers using DDU each time.
-all sorts of tweaks on settings, setting everything to low medium hugh,
-playing around with Nvidia settings following tutorials
-Formated my PC entirely and reinstalled win10 from scratch...
I've read up on many forums and it seems the higher end your PC is the more likely you get these issues.
This is extremely common according to my Google research and forums read.
It's really time EA looks into this.
