If your PC shuts down, it's likely a failsafe due to overheating hardware. This game has high CPU usage, resulting in higher temperatures.
It does run a bit hot like he says if you use specy you can see how hot your components are running you can also use MSI afterburner to increase your graphics fan speed which won't harm your card in any way both are free programs. I personaly never had it exceed 130F on the card and 110F on my processor with three case fans of course my processor isn't overclocked if yours is that causes a large amount of heat two and really no need to do such
