Im getting wicked game crashes even tho my usage is maintained under 70%

I duno if this game just hates pc mouse/keyboard software or what but Im getting stutter that just crashes almost everygame with my razer synapse software. which blows chunks cuz its an analog keyboard and i need it to act like a joystick. I can see on steam charts the games getting a LOT LESS players and im assuming its crashing all to hell on pc. at least through steam. I duno. sad stuff!
