Mine just crashed (again). In my estimates it's maybe once every hour of gameplay.
Specs - Ryzen 2600x and RX580 8gb. No perfromance issue playing on 2560x1440. Windows 10 home version (original).
Experienced maybe 10 CTD's during 300+ hours on earlier Perisno versions. Battle size is ~800 through the "Battle Sizer" (changed from 378 after the second CTD).
I'm a male dwarf in day 14. Zaira, Thrak, Slyter and Tylen as companions. My character has the same gear i had exciting the mine (used that start) except weilding Nisayian's Legacy and have a pony.
I have a very diverse party with a few of each: bounty hunters, mercenary stalkers, kaikoth footmen, a few bakhal soldiers, Drahara wind archers, drahara elite spearmen, perisno novice and just got 3 elintor recruits. A total of 34 in the party.
Setting: Just attacked a Anakars party of 14. They hade 14+40 So thought I could get some money from prisoners and maybe recruit a few. Everything went well, they hade 2 riding archers left went the crashed. Froze for 3sec then went back to desktop.
I checked "Load textures on demand" and it's on.

Update: CTD again
This time I was in a village to track down a murderer for a lord.
Just when I land the killing blow I went back to desktop.
Never had a CTD outside of a battle as far as I know.
