Requires Media Foundation workaround - see https://github.com/z0z0z/mf-install

However even after mf is installed the game suffers. Alt tabbing will make the game unresponsive, as is clicking anything while the first menu is loading. Windowed mode does not work; the game also slows down over time and by minute 15 it is sluggish and stuttering. Finally, quitting the game isn't registered by steam which prevents it from restarting without closing steam as well
