I get this weird flicker in my game it happens like every couple of seconds and its really annoying. But its odd because the tiles themselves dont do it, just my character, items on screen and any of the words and numbers in my sidebar. It kinda makes it look like those things mentioned get slightly darker for a second and then lighter again after a second or two and then darker again, and repeat every couple seconds. Its making it a pain to play.
I seem to have fixed the issue by changing the renderer from D3d to D3d11.
