Adding my 10 cents.
Was having the issue of a black screen and then my drivers rebooting and the game working again.
Now it hangs as soon as the launcher comes up, every time.
I’m running a gtx 580, with the latest WHQL drivers (though the issue was occurring with the previous 2 iterations of beta drivers), i5-2500k at normal clocks and 8gb of RAM.
I’ve uninstalled the game in the meantime and will try a full reinstall tomorrow, but most frustrating!
