actually i have a DELL Inspiron 15 , with IntelHD4000, Intel Core I3, i run the game smoothly in medium with 25-42 FPS using a Command line,but sometimes i lose graphics (textuers), but that lag fix for Core2due users or less, but all i mean that its not safe, look at 0:15 in the video you will notice me coming in Chris way ,it was like a surprise , everything is hidden like a foggy weather
