Lighting issue

While it may be a game issue, more than likely you have something going on with your rig. For example, I have a recurring "screen going black issue" which I traced to my KVM.

Try a different video cable, update (or revert) your GPU drivers, etc.

Very unlikely this has anything to do with my configuration.  It is an issue with the game. The lighting goes dark incorrectly., seems to be worse on the Eastwood map and was not like this prior to the most recent update. 

I will try capture a screenshot but I noticed screenshot capture seems to change the brightness, so may not be ideal to capture.
