Fortunately stood in a forum on how to fix the error.
Under "Graphics", "Quality Settings", "ambient occlusion" simply switch to "SSAO". Then everything looks normal again. :-) ;-)
Otherwise, it plays like Far Cry 3. It hunts animals to turn their skins better tote bags and belts (I find the idea of super), can swim, walk, fly or drive. The story? Have only played a few hours, but I think now that it is to me worth 4 stars.
