Vray Blurry reflection Material settings

[swat820]

I'm having a problem of setting up a concrete material that should have blurry reflection and proper textured.
I uses 0.01 of Displacement map for bump
0.7 of Glossiness with Fresnel map of 4 IOR
is there any possible way of improving it?
Its rendered with IM 5 passes + LC 5000sub
thank you so much

Re: Vray Blurry reflection Material settings

First I think you're using too high options settings (if this is the resolution and some). Displacement is not necessary, in this case you can get away easy with just a bump map.
What is the Highlight/reflection glossiness? or are they both 0.7?
There are all kind of concrete textures/finishes, so please post a reference image of the concrete you want to produce.
