My wife and I are playing a mutliplayer game together (bought the game today on Steam), and she is unable to see certain environmental effects (poison or fire on the ground, etc), and now we are in Zixzax's observatory with the giant telescope and all she can see are stars with a few braziers and the waypoint portal.
We both have AMD cards, she just updated her drivers to see if that was the issue. Our graphics are all the same as well. I had her verify integrity of game cache, no dice, so she re-installed the game and is still having this issue.
