Flickering

[dcwillgetback]

Hi

I am working on a Frosted ice kind of shader in Maya 7.0. The look I am getting is fine. But I am having flickering issue with my bump Texture. My scene has got Reflections,refractions,Transperancy and bump in the shader. I don't have any procedural textures assigned to my shader. My bump texture is a 3K texture. I have also tried jacking up the sampling and the texture filtering but I am still getting flickering because of the bump. Can anyone help.

Thanks
