Hi Vins, I am running Delta3D terrain simulation & VPB built terrain on some quadro card on Linux 64-bit system without any trouble...
But it might be different, as I've not such big database as you are talking about and the terrain is not a terrapage file. Does the problem only occur on very large database ? What is your standard card vs Quadro card ? What is your driver version ? what is your system ? If it is not a driver related problem, it might be a problem with some VBO/PBO functions... Pierre.
