Shane,
I hear ya. Not that I think you haven't tried this but just in case. I had a similar problem with gamma and brightness. I discovered that my contrast settings had a darkening effect also. When I had a graphics card (currently struggling to put a system together) I constantly played with brightness, contrast, gamma, sharpness, and digital vibrance. Just when I would get it set, a new update would come in and I would spend hours adjusting it
I was making the adjustments long before no icons. My eyes are deteriorating very quickly and I need the extra "pop" in color to identify outlines of enemies to determine their attitude towards me. Very difficult to judge a plane heading at me or just stalled. I have both zoom options mapped to my joystick and boy do I use them.
Nice shooting Cap! Anyone we know?
