A temporary workaround is to enable Vsync in the game

So, as seen in the known issues, they know about the problem with DAI and mantle (to be truly, none of mantle games I've seen works perfect with this c&*p). So, turn off the mantle (using DX11) is the workaround by now for me.

Anyway, the little stutterings for AMD cards are solved in this beta, so I recommend it.

Cheers
