thin objects render errors with GPU

[andreplx]

hello i want to render a thin object. its basically an outline extruded to .075. a foil.
it is meshes in grid manner to apply deformation.
rt gpu produces render/smoothing?-errors around the vertices of the planar part ( the top-plane).
rt with cpu renders correct.

Can you show me? Also, can you send us the scene to vray@chaosgroup.com so that we can try to figure out a way around it?

Best regards,
