I'm using the latest version of Dyndolod and my game crashes at the same location (near Helgen Cave), it seems that occlusion.esp is involved, see crash log.

Ok thank you, I read on reddit z fighting problem causing by high fov, I had increase the FOV to 100 in skyrim.ini, I lowered it to 90 and regenerate TextGen / DynDolod with higher values, problem solved.
