I've been running dx11 for a few weeks. I have had only one, very obscure, rarely occurring issue that even hitech can't duplicate. Is it possible those folks with dx11 issues should not be running it? Not sure about AHIII defaulting to the preferred version; I had to select one, but that was early on. FYI, my issue is simply that when flying hotas, I sometimes minimize to the menu bar just like hitting alt tab. When I click on the AHIII icon, I'm right back in the game in the same status as when I minimized. SKuzzy may have given us the fix for that. Haven't had a chance to test that.
