So I updated my drivers today to Catalyst 15.7.1(July 28 2015). Whole slew of problems with this game after when trying to run DX11.

2 and 4 both resulted in the game stopping interacting with windows and forcing me to close it. I had the in game mouse cursor but the window just wasn't there, I could see everything behind it(browser, etc) but couldn't interact with them until alt+tab program switching.

I could *not* alt+tab cycle back to FFXIV, it wouldn't respond.

This is starting to piss me off. You add a DX11 client, which looks absolutely *fantastic*, but it's so plagued with problems and there's threads all over the damn place complaining about it, but there's 0 word from SE about it. Nothing. It's like you're ignoring it.

*sigh*
