Hey there.
This happens every time I start a game, after a few minutes of game play. The brightness uncontrollably goes from normal to way way over blown, to the point that I can barely make out any objects. Also, it's a bit slow and choppy, but I can fix those by turning the graphics settings down.
Specs: Processor 2.5 GHz Intel Core i5, Memory 8 GB, Graphics AMD Radeon HD 6750M 512 MB.
Specs of note: I am running this on a Mac with Parallels using Windows XP.
Not sure how to include a screen shot of it, but I have some. Basically, imagine an explosion of white. Imagine you got your eyes dilated three times in an hour. That's my tragedy.
Help please and thanks.
