I recently bought the Penumbra Collection and in all of them I get an odd display flicker that moves up the screen repeatedly and greatly distorting my view. I've messed with my resolution, turned off all effects, tried working with different frame rates (always made it worse). I double checked my drivers and all of them are up to date and downloaded the patches.
My system specs are in my sig, and a picture of the distortion is below. The shaded area in the pic jitters up across the screen repeatedly even while in the menu's and title screens.
