Sorry to keep bringing this up guys, I do apreciate all the responses I got last time. Ok now, I'm still researching the subject and I still can't find any solid evidence. I did recently get my eyes checked and as usual I have perfect eyesite. No color blindness and I've never had to wear glasses. If someone can give me an example of an image and show it rendered in 16 bit and then 32 bit and show a big difference then I will shut up but so far I can't. I have taken screen shots from various new games in 32 bit mode and then analized them in my image software and counted the colors used and all but one game weighed in at well under 65,000 colors and the only one that was more was about 70,000 colors which still didn't look any different in 16 bit mode to me. I still haven't figured out why 32 bit colors are refered to as the same as a 24 bit color, I think it's because we can't see it anyway. In fact i'm willing to bet we can't even see true 24 bit colors, c'mon thats 16 million different colors thats got to be impossible, theres a big difference between 65 thousand and 16 million, its 256 times as many colors and then there is 32 bit which should be mathmatically 4 billion colors. Impossible I say, I think it's a bunch of bull and if our computers are actually running in 32 bit mode then we can't see it anyway and your smarter to run in 16 bit and and jack up the FSAA so you can actually make the image look better. I dare anyone to prove me wrong! please!
