Not much of a difference, but DX10.1 feels a bit smoother even tho the fps are a bit lower. Try it for yourself ;)
PS: DX11 is only usable at night, on daytime all completely shiny. I ran a benchmark with it tho and it doesn't give better or worse performance. It will only make a difference if we reach the point where we can max out the graphic settings. Will try that later on i think.
