Alt + Enter in Dx11

[Luciferstwin]

Anyone else having a problem when you hit Alt + Enter at the same time in Dx11, that it will somewhat crash your graphics drivers? Im not sure if it actually crashes them, but both my monitors flash to a black screen, then come back within a few seconds. No display driver error or anything, just comes back like as if nothing happened. It doesnt happen in Dx9, only Dx11.

This is happening to me as well.

Alt+enter combo has different uses, but here we are talking of altering fullscreen mode. So it is trying to change your screen mode. It takes time depending on system, but for u not to worry there are a whole lot of developer's threads about "DX11 and alt+entrer" and some threads about changing screen mode under DX11 on this forum.
TL;DR It's not driver crash - it's your system changing screen mode.
P.S. I'm also having major problems cause I use software for using multiple screens and somehow FFXIV under DX11 doesn't want to be friend of my system. Under DX9 it's all perfect thou.
