Lag when shot/shooting/encountered enemy

As title says. Lag spikes during those events, and my FPS grinds to a halt.

I'm using GTX970, i7 4790, 16G ram and using lowest possible graphics option except for scope detail.
The scope detail can be lowered but still has the same issue. Anyone else experiencing this?

Same specs basically same problems. It's better after the hotfix but it's still barely playable.

Edit for the brainless "u'r pc sux" crowd of brainless zombies that is bound to arrive: This problem did not exist in Beta 1.

Yeah, I know it is not my PC, because I am having more issues this beta. Everyone in game was like update your drivers, and change your settings. My response, 'you think I hadnt already tried that?'
