Scott over at TR has sent along an addendum to his X1900 review. He's reporting an image quality snag in 3DMark06 that he experienced while benchmarking the X1900 series, & ATi has responded to his inquiry on the matter:

"Pixel shader programs are compiled in the graphics driver, of course, so ATI should be able to fix the problem with a driver update, and that's exactly what they expect to do. We don't yet have any ETA on the fix, but ATI claims it should not adversely affect performance. We'll have to see about that."
