When flying a night mission my NVGs seemed to start out alright, but the view got pixelated in a grid-like manner; and it got worse as gametime passed by. For a while it looked like this (http://imageshack.us/photo/my-images/812/nvgbad2.jpg/)
Then after that it looked like this (http://imageshack.us/photo/my-images/341/nvgbad1.jpg/)
Then after that I started to see lines on the ABRIS (http://imageshack.us/photo/my-images/651/nvgabrisgridlines.jpg/)
I have an ATI 6950 with CAT 11.10. Some of my game settings are: HDR: off, Water: Low, AA: 4x, TSAA: on, VSYNC: on, Cockpit Shadows: on. I loaded open hardware monitor halfway through to see if it was an overheating issue, and GPU temp. never got above 62deg C.
