Lag episodes near Squin?

[holografix]

when I'm near Squin (up to Admag too) I get fps drops from 75 to maybe 10 (didn't measure). This lasts for about 10 seconds, it's pretty much like an invisible loading state. I have explored the whole map and while I think it might be a somewhat regular occurence it is very noticable in that area. I was able to reproduce it without mods. And I can reliably reproduce it if I approach Squin from the west walking from about 500 to 300m distance from it. It happens if I walk back and forth that distance.

When I first noticed this I thought maybe the AI trapped itself in some loop or so.

But now this is also happening in a new game, and I also re-imported.

My CPU usage does not go up though. I also used radeontop to monitor my GPU and pretty much everything (except memory usage which is at about 50% of 12GB) goes down in that period. I'm not sure if this is the bottleneck though.

Can't really imagine that it's my system specs:

Intel Core i7-4790K
16GB RAM
Radeon RX 6700 XT
installed on Crucial MX500 1 TB

I'm using Linux and when that happens wineserver goes up to 4% cpu or so, but it also does this in normal loading scenarios.
