GOG has a design flaw in its client where you HAVE to install this DLC if you own it, unlike Steam where you can pick which DLCs get installed with the base game, unfortunately you cannot do that here, you have to install this 50+ gig texture pack. Even if you download the offline installer and just install the base game, GOG will try and "patch" this HD texture pack into the game everytime you launch GOG. No word on if this will get fixed. Buyer beware.
