I'm having the same prob and I'm running a core i7 and 2 months ago installed a GTX 960 I have deleted bitraiders (?) lowered graphic settings sent support an email and they gave me links to check my drivers,bio's, etc. and its all good on my end according to these links. I constantly have freezing up it doesn't matter what I'm doing or where I'm at. I even did a re-install and its the same. I just recently re-subbed and this is getting really frustrating. Thanks.
