Weird banding issue in Medium - anyone else ever experience this?

Had to switch out my videocard as my last one died - now using r9 280 until I can afford something beefier. Aside from some laggy framerates here and there, everything works fine - I just get this odd banding when working in Medium. Its just a visual glitch - nothing exports like that, just annoying when I'm trying to sculpt.

The banding on the surfaces is unavoidable, but can actually help see errors in the shape.
Yours looks different though.

yeah - the moire' effect in the jet image is pretty common - the banding I'm getting is thick and dark. Wondering if my old r9 280 doesn't have some of the advanced rendering feature of newer, better cards

I'm fairly certain that the banding is due to a combination of slight aliasing in the surface mesh.and the way the Ambient Occlusion algorithm works. It should go away if you turn off AO in the material pane.

Sorry, I thought that the plane was the banding issue that you were seeing. The texture banding in the image in your link is a common issue seen with certain AMD cards and driver combinations. About the only thing you can do is to try older versions of the drivers and hope one of them clears the issue.

Matt Hickman chimed in about the problem in the following thread:

Capture a dxdiag report and send it to their team so they can investigate the problem.
