Hello,

does VrayRT make use of multiple SLI gfx cards? Let´s say you have two nvidia 295 gfx cards in one system.

Thanks,

Currently V-Ray RT is completely CPU-based.

If you are referring to the GPU version that we showed at Siggraph, it is a bit too early to give any particular hardware recommendations.
