Just started playing SS2 and during gameplay I get an intermittent black screen for less than 1/2 a second a time. I've seen forums about texture flickering but nothing relating to my issue. It's not a gamebreaker as it is so brief but can be a little annoying.

I'm running, Win 7 x 64, Nvidia GT-420M card and the game is installed in my C;Games/GOG folder.

Any help would be appreciated. Thanks.
