RT GPU will not render maps, other problems too

[Rob Burns]

I am running max 2012 with all current SP's and hot fixes, vray 2.25.01, and have a GTX 570 with the 290.36 beta driver. Here is a comparison between vray CPU (rendering correctly) and what RT gpu is giving me. Basically RT gpu is not showing any maps (even though they are all properly configured using UNC paths) also the interior lights should be invisible, but they are rendering visible. RT gpu was rendering correctly before when I was using a quadro fx 3700. Any help you can offer is much appreciated.

Is it on any scene, or just this one?

It is the same problem with all scenes. It seems like there is a problem with certain procedural maps, like rgb tint and falloff. Most of my diffuse maps use rgb tint to adjust their colors, but if I remove it and just us the map directly it will render o.k. in rt, minus the color adjustment of course. Not sure why invisible lights show as visible though. There are other problems too, like if I use large opacity mapped rectangles as reflection billboards it will cause rt to hang and freeze my whole computer.
