Since patch 4, I get these weird light and shadow ripple lines on everyone if they're in direct light. It occurs on certain surfaces during regular play too. Any suggestions on how to get rid of them? I've tried flipping windowed mode to fullscreen, turning off shadows, turning shadows to max, changing the frame rate, changing the antialiasing, nothing seems to work. Anyone have any advice?
