Stuttering shouldn't be happening constantly (i.e. non-stop). If it is, the problem is elsewhere.
If you're talking about occasional but heavy stuttering while in a map and entering a "new" area (or going back to an area you haven't been in for a while), that is absolutely due to AI generation.
The forum here has talked about how to minimise it, with the only option being choosing "Low" for "AI Amount" before you go into a raid.
And for me, the issue happened on 2.0.1 as well. The stutters weren't as long/heavy, but they happened under the exact same circumstances. They don't upset me very much when they happen.
In short, it's a known annoyance, but it shouldn't be happening non-stop. It should only happen occasionally when PMCs or Scavs are generated, and not happen again until more need to be generated. I also don't see how this could be alleviated; maybe it's something that "real" Tarkov generates server-side (meaning, on a completely separate server/machine and not your computer), and thus the processing isn't happening on the client like with SPT-AKI.
