Doesn't run in full screen mode on my laptop, seems to have problems with the nvidia gpu on the laptop. This type of crap shows a lack of testing, like they just threw it out there to see how much they could make with no work. GoG is really hit or miss these days. Wish they would take their business seriously, they have potential. Guess this is why most people just go with Steam.
I loved this game when I played the box version, but the GOG version's graphics are so bad, it is impossible to play when the game is at night. And, there seems to be no way to adjust the contrast, so you basically have to just wait until the game's dawn before it is playable again. Have not gotten to any dungeons yet, but I assume they are also unplayable. This is by far the worst GOG game I have bought out of over 100. How they messed up the graphics this bad is difficult to imagine. I have an nvidia graphics card, so it isn't like I am using some strange graphics... Recommend you hunt down the boxed version, this is unplayable and a waste of money.
