Major BUG Report. (Crash, Hard Reset)

Hi,

I’m experiencing major rust bug. Computer complete freezes while playing rust, and requrest hard reset. It’s completely random, sometime I can play for 1 hour, sometimes 3 hours or sometimes 30min. It’s really annoying when running around with loot, and freezes computer randomly requiring hard computer reset.

Running Mac Pro with Windows on it (http://www.apple.com/mac-pro/specs/) GPU is AMD Firepro D500.

Is there maybe some gaming settings/graphics I could change?

Here are the complete specs.
