Constant crashes/low fps in Orb Vallis/Plains of Eidolon

[shinmikomi]

As the title says, I'm getting constant crashes and low fps on and ONLY ON(I thought that could be important because I'm also getting low fps at the railjack anomaly, but the game doesn't crash) the open-world locations. Usually the game crashes on transitions, like when im qutting the Fortuna or Deck 12. Sometimes the game just closes, sometimes it shows "Insufficient video memory" error. The problem is, Firstly, it happens on any settings, no matter if I set ultra or minimal, I'm getting low fps and crashes. Secondly, I have 4 GB of video memory and I've seen people playing well even on 2 GB. So I'm wondering if the problem is with my PC or drivers, or may be some memory leak happens in the game. Also, I've monitored my video memory on "transitions" and it really immediately jumps to 100% of usage, but the game crashes only in 1 out of 7-8 cases.
