What are the Advantages of the SLI Technology for Processing? - PIX4Dmapper

In terms of processing, using SLI technology would not help the processing since it would not increase the available RAM, which is the bottleneck for processing.

SLI would improve the rayCloud visualization for very large projects.

Having two GPUs not connected using SLI would improve the GPU performance for the processing since the state of the GPUs is periodically checked and the less busy one is used. For more information:Use of the GPU in PIX4Dmapper.
