Screen tearing leading to game crash

So i played in beta phase 4 without any problems at all, but now in early access i can't get past the intro because of screen tearing which causes my game to "stop responding"....

My specs:
AMD FX 8150 eight-core processor 3.61 GHz
32 gb ram
windows 7 64-bit
AMD Radeon HD 7900 series x2
AMD Radeon Graphics processor
Display: 1920x1080 60Hz
Running directx 11

Please help me, i love this game and would like to actually be able to play it..

*Edit*
I tried benchmark now and got a 9100 score before screen tearing caused that to crash as well
