First make sure you aren't shorting your high poly sculpt by creating a low res texture. I shoot for 1 million polys = 1k texture, 2m=2k, 4m=4K, etc.
In the DispMod use Subdivision. Set Filter Blur to 0.0 (don't trust the checkbox). Set edge length to .001. Turn off view dependent. Set subdivision to match the number of subdivisions you had in zbrush (it defaults at 256...which is crazy high for this workflow)...you won't need the turbo smooth by the way.
For your bitmap loader, use VRayHDRI. Use Eliptical filtering. Set color space to none (assuming 32 bit exr). Turn the blur down.
Hope this helps!
