Hello!
Tonight I've played a besiege (on Helm's Deep) with a friend (it seems possible since the 5.1 patch) but a crash happen 20 minutes after the launch of the game.
It's not the usual " Direct3d 0x0x8007000e ", I attach an screenshot to this post.
For precisions:
- I'm on 5.1 Age of the Ring version
- 2.02 v8.0.1
- LAA Patch is installed
- No shadows and low shaders
- on nvidia: in attached files
Thanks for the time to answer me, and a great thanks for this loving mod
