Picture going white where it's light, but in the dark everything looks good

First off, this is an OpenGL game so DirectX update does not make a difference. Secondly, the game is not full of bugs. It works just fine with the hardware that can support it. Run the Amnesia demo to see what graphics card is being used. If it is the Intel one, then it is known that Intel cards do not suppot Penumbra.
