Re: [Old Report] Witch Hunt dlc crashes during Lights of quest

I don't mean to necropost, but this is the first post I came across while googling, so thought I might add it here for future googlers.

I just encountered this problem and struggled a fair bit, then remembered I had the same issue in Denerim a long while ago, and the trick I found to fix it, which also seems to have fixed it here.

Before all that, you can also set the compatibility of daorigins.exe to "Windows xp Service pack 2" and run as admin. It might fix things.

Now for the tricky part :

If you open the task manager, select the Daorigins process in "processes", you can right click to go to details. From there, right click on the daorigins process once more and select "Set Afiinity". Here if you untick all the CPU except CPU 0, it should solve your issue. Granted, you'll get some small lag in game, but you'll be crash free. 
Please note that this is not to be attempted if you have to google "open task manager" 🙂 I doubt it'll break your pc, but let's not push it.
