Hm, you know, it seems quite a widespread problem.
Even this guy...

...has it. (See second picture.) Someone comments that they have the problem too.
And apparently people have been posting about this issue for months on these forums. The "white glitter"...
It clearly effects both ATI and Nvidia, and cards of all types, so the almost knee-jerk reaction of, "It's a driver issue" should be dispelled.
But not everyone has it either...
I wouldn't expect a fix from a patch. If you can fix it on your own, fine, but not everyone can do that, and Stardock doesn't care.
Hm, I'm not sure I'll buy this game.
