Ok, We have never heard this before. Works on every normal PC also without a graphics card. Can you check in your Task Manager -> Performance if the Game draws all the Performance?
I'm now in menu and my pc sounds as if it was preparing to fly. In Task Manager is shows me that 1st thing about processor is 60% and the last one about my videocard that is GeForce GTX 1660 is 99%... eventhough I'm in the main menu
