I agree with the OP that a vast majority of players should have graphics cards that now support DX11. I think it came out in 2009 at some point. I know some people still use Windows XP though and that might pose an issue regarding the importance of DX11, but I feel as if this game would really benefit from a true DX11 executable. The game already looks great, but all the additional effects, it just makes me drool.

So, I hope that there is some real effort put into pushing out a DX11 client when the time is ready, I know many people would be thankful for that.
