Here are two screen shots that illustrate the problem I’m dealing with. It wasn’t doing this a patch or two ago… and Vulpto seems particularly bad.
The effect creates a bright and dark flashing that I can control a bit by looking more at the ground. When I turn my character’s face up toward the horizon or the sky the ‘fog’ is illuminated and the screen becomes very bright. There is no flickering if I don’t move. It’s based entirely upon the angle at which I’m looking.
Ok, from my casual, amateur perspective there seem to be no chunking issues. Here are two screens with the bright fog… and without. All I have to do is move my mouse a hair down toward the horizon to get it to stop.
