I had to update my Physx version to the newest because it is required by another game that I just got. I started up Divinity 2 and it came up with a message about having a different Physx version and that if it causes problems go here. I played for a little while then the game crashed and caused the video to mess up. I tried to fix it without restarting but it didn't work and then I got a BSOD and had to shutoff my computer. The video works after Windows 7 comes back up and I put the older Physx version back in and don't have a problem anymore.
