I start the game and the fps just like disappears and the cpu usage goes up like crazy then it crashes. At first it ate all the cpu and I had to manually reset the computer. Then I tried a fix to the memory leak where you set priority to low in task manager and in set affinity I unticked the last core. After that the PC didn't crash along with the game. I played it fine without problem earlier (9th March 2017) at 20:00-ish. but when I tried later at just after 21:30 the problems described earlier started.

EDIT: I disabled UPnP and it works now. I didn't think that was the problem seeing as it doesn't work (ISP or Routers fault) no matter what I get NAT type strict.
