Hello horriblesleep,

It seems that this has something to do with your graphics drivers or display. Are you using SLI? It seems that it is failing to retrieve your SLI state meaning that it’s currently set to null. Can you check your Nvidia settings and/or reinstall your drivers?

We haven’t heard from you in a while, horriblesleep. Are you still experiencing this issue? If so, was my last comment of any help? In the meantime, I’ll be marking this issue as resolved for tracking purposes.
