Direct X 11 Issue in editor and game view

Hi everyone. I noticed that when I enable DirectX 11 on my project, both the editor view and the game view become very laggy. I´ve tested this on Windows 7, Windows8 and Windows 10 and the problem persists.

Its like everytime I provide any input to the system, like Keyboard or Mouse Events in both modes, the interaction lags for a fraction of a second, i.e. Camera manipulation, interactions in the Editor´s Panels and so on...

When I disable DirectX 11, everything goes back to normal.

Does anyone had a similar problem with this?

(By the way: The Topics text field in this page sucks big time, it never lets me add my tags correctly, it keeps getting in the way)

Thanks!
