Because I have vista it won't allow me to even get a screenshot with F12 for some reason.
But when going into sneak while wearing shirts that have a collar, it will either switch colors/transparency depending on where I look or what's going on. For example: I'll be wearing the system suit and I can see through to see the outline of the collar and it's usually a gray-transparant color. But when looking in certain directions or depending on the situation, it'll turn into a brighter white and slighly less transparant. Also, every now and then, it'll turn into a blue-green transparant color as well.
This only happens on the collar. It's similar to what happens when wearing the commando suit in sneak, and the gray-transparant color of the body will turn black.
Is it Vista, the game, or the graphics card or drivers?
Btw, graphics card is: 256mb 8600GT nVidia GeForce for my laptop.
