Interesting, why downgrade the textures ? To somehowe make the difference more pronounce when installing the HD Pack ? This is shady play from WH if it’s not a bug. Btw, there are others who noticed the difference first.
UPDATE 1: I think i know what is going on, every time i go to Graphical settings, My settings are reseting to HIGH from ULTRA. When changing it back up to ULTRA game needs to be restarted.
UPDATE 2: Patch 1.41 Helped, working as it shloud. Case Closed
