Can we use somehow 2 vray displacement mod. in one object?

[larex39]

Hi i have very complex model and i need to first subdivide it with vray displacemen modifier (like turbosmooth) and then displace it with another . If i do it only with second modifier, it is not smoothing model only displace it. When i use both i figureout that the last vray displacement modifier overwriting the first. Of course i can put tbsmoot and turn it in rendertime, but even only having or asigning this modifier on model is slowing my max interactivity like a hell. So is there some workaround to make it works?
Thanks a lot

Alex.

hmm strange, it should work
maybe try a different texture channel for each vraydisplacementmod?

What if you used a subdivide and set it to not display... same lag? Odd.
