Vray denoiser problem

[design18]

Hi

I have been rendering 3d views in 3ds max 2010 and vray 1.5...and i get pretty good images..

Now i tried 3ds max 2015 and vray 3.5 and the rendering time has reduced drastically..

But i am not getting the desire image quality..

My clear glass material is looking like frosted glass in vray 3.5 because of Denoiser...

without denoiser image looks very noisy...but with denoiser glass materials are losing its refraction values..

I tried using all channels instead of colour only ...but still its not working..

Please let me know the solution for this.

 

 

Thanks
