They're checking it out.
One of the upgrades we have done on the game is that whenever there is a crash, it will send us the hardware config (like Windows error reporter) so we can look at the video driver / card combo and see what the deal is. And since we live in the age of digital distribution, we can update the game quickly if there's a workaround.
The challenge is just trying to get the right hardware set up to reproduce it.
