You seem to have a performance problem with point cloud rendering. Multiple graphics cards rendering is a far-fetched approach when it comes to interactive graphics. There are smarter ways to improve performance which I pointed above.

Still, if you are quite very firmly sure that is the only absolute single one way to solve your issue, please refer to this: [Rendering on multiple GPUs? - #4 by jaswantp](https://discourse.vtk.org/t/rendering-on-multiple-gpus/837/4)
