This is a strange one, and I'm wondering if anybody has any ideas. If my brightness is set to default (fGamma=1.0000), when I load the game, the displayed brightness is incorrect. The setting in the menu looks fine, but the display is much too bright, as if it were about at the 3/4 mark instead of half-way. If I change the brightness by a notch, then put it back, the brightness reverts to what it should be and stays that way on subsequent loads within that session, but then it's back to the 3/4-ish level the next time I launch the game. I've tried removing all mods, resetting all preferences, all that jazz, and none of that works. The only thing I found that works is to set the fGamma to something other than 1.0000. Even setting it to 0.9999 is sufficient. Any ideas what's going on here?
