I have a i7-2600K 16GB Ram and a GTX 570 Video Card. I'm running WIndows 7 Ultimate 64bit Version. When I play the game there are two problems. When the intro video starts it pauses in certain places for about 20 seconds then continues. Then when I get to actual gameplay the screen flickers and will go all black except the area around my cursor. I've I move my cursor it will erase the black and eventually the screen will flicker and go back to normal and then repeat. Has anyone had this issue and if so do you please know how to fix it? I don't have the GOG Version as I have a retail version. Any help would be greatly appreciated.
