Might and Magic Heroes VI expansion Shades of Darkness has a bug which makes most of the screen appear black on Intel cards.

Shadows can't be disabled ingame but perhaps reshade could help fix the issue by disabling what ever causes this problem in the first place.
Would you be so kind and tel me if it is possible and if so how? Thanks!!
