Vray RT GPU issue with Nvidia GTX 580

[blackbox]

HI
Has anyone else got a Nvidia GTX 580 graphics card and tried using vray RT GPU?

Even for the most simple of scenes i get very strange results. The VFB opens and an image appears but quickly fades to black, in the cmd window i get lots of error messages saying ...

error Invalid command queue (-36) at line ......

this eventually leads to Maya crashing.

I'm using Win 7 64 bit - Maya 2012

I have tried installing different versions of the Nvidia drivers but with the same results.. not sure if it's a GPU driver issue or Vray or my system!!??

Any thoughts anyone?

This same system with a an older Nvidia 285 GTX card worked fine with RT GPU.

cheers

Please try driver version 270.61:

and if the problem persist, please send us full output of the V-Ray console at support@chaosgroup.com , and include information about the V-Ray version you are using and the scene.
Thank you in advance.

HI Tanya
yup that is the driver i'm on.
Sorry for dumb question but how do I send you the console output when Maya crashes? Is there a .txt of it stored somewhere?
thanks
