I posted this on the general forum and someone suggested that this should be posted in the tech support so that the blues will know about it. This is regaurding the latest nvidia drivers that were released today. Several people including myself have stated that these drivers causes crashes and in my case, the screen flickers in fullscreen mode, once every second. Reverting back to previous drivers solves this problem. Just a heads up.

Thanks for the reports guys.

We are currently looking in to this issue and hope to have it resolved in a future patch.
