I would also check your cooling system. Maybe run a temp check at the same time as doing a map. I had a video card that would overheat in 5 min of opening ark, no matter what I was doing on it. Could be the software running your fan speed might be slowed down in the process. I have a 32gig, 8 core rig running gtx1040 now. It takes about 5 to 8 minutes to conjure up a new map. In that time I hear my fans turn up in speed. There is software out there for free to turn your fans up manually. Also check for dirt in the heat sink..
