After spying in on the conversation directly outside of the ruins, the game hangs when the robed man moves to sacrifice his three followers. The audio plays but the animations do not, and the game simply hangs in silence after the audio. Is there potentially a workaround to skip this 'cutscene' or am I simply stuck until that's fixed? 

FWIW, I have this exact same problem. 

Enter Graphics options and try a lower resolution. That has worked here with 1440x900 instead of 1920x1080.

I killed the game via Alt + F4, restarted and continued.  The cutscene played properly this time.

I have my graphics options at minimum 1280x720, restarted 3 times to no avail so far. 

We were able to reproduce this on our side shortly after being reported today by artificially lowering the framerate a lot and starting the cutscene. This seems to mainly trigger when framerate is slow. We have a fix in for our next patch coming out soon but in the meantime, try lowering your resolution to the lowest possible setting and turning off anti-aliasing.

 

To turn off Anti-Aliasing press the ` key to open the console and enter "msaa 0" and hit enter.

 

Hopefully that will increase your framerate enough to bypass the issue. This also seems to be the only cutscene effected.

Removing the AA doesn't fix it but it is nice to hear that this already has a fix queued up. Thank you for the response.
