Be it that Im flying in the winter of 1916, I have often been facing some rather unpleasant weather: clouds, rain, snow, fog, sleet, etc. I do experience an occasional flickering or disappearing and reappearing cloud from time to time. Nothing that is too much of a bother, but is there a graphical override setting I can set so that the clouds don't do this? I recently upgraded my video card from a 9800 gtx to a 460 gtx but both have displayed this occasional quirk so Im guessing its not the video card. Or is it perhaps the result of some corrupted file in OFF? Again, not a major issue, but just curious if anyone else has run into this and if anything can be done about it...
