The first time I had crashes in DAO was in the circle of mages.
After a long fruitless search, I tried turning of full screen mode.
I never experienced a crash in windowed mode 😉, but full screen is way more enjoyable of course.
This is however a very simple workaround that I used in the circle of mages and in fort drakon. There was a third area where I needed this but I can't remember which one. After the critical areas I switched back to full screen mode (until the next crash).
Switching from full screen mode to windowed mode:
Game menu: Video settings: Remove check or
DAconfig.exe: Video settings: Remove check (also accessible via autorun under configuration
Have fun playing 😉
PS: Other people solved this by
- turning of "effect buffer" in video settings (http://forums.steampowered.com/forums/showthread.php?t=1697204) or
- increasing the number of used cpu cores (http://steamcommunity.com/app/47810/discussions/0/540742579540744334/)
If windowed mode does not work for you try one of these solutions
