Well fellas I tried about 10 different driver versions, and I get the same issue, the only time the sun has that nice corona around it is when I disable the darn AA. If I set it to 2x, 4x, 8XQ, 8x, 16X, or 16XQ, I lose the nice lighting effects, and the rest of the picture looks like it's running in 256 color mode.
So it's a tossup, nice picture with jaggies, or substandard picture with no jaggies.
What a pain.
