Pokemon Insurgence crashes computer

I got through the beginning fine in the cult of Darkrai. (Although there some random lag spike) But when I get to the scene of the cult summoning Darkrai, it stops responding and my other programs that I have open stop responding then I can’t move my mouse. I have to turn off my computer. Can I get some help on this?

Are you running on Mac, Windows or Linux?

I’m on windows and I just recently found out during that cutscene, it takes a lot of CPU.
