What graphics card are you using, if it's alright to ask?
When I started the game and the LavaLamp Games logo appered on screen but in poor resolution. When I got into the game menu, the whole screen seemed to have a flicking overlay of rgb. It would alternate between the colors very quickly and seemed to have no pattern. I could still see the game behind it. After spending about 5 minites in game I could see no other problems besides the screen. I hope this helped.
