Hi all,
I'm using 4.04 LightWave plugin and have just jumped from two 1080 Ti to three. I have also bought an Amfeltec Multi GPU Cluster to house the excess cards, but I am finding that any card installed on the Cluster is running about 50% slower than an internal card. A scene that an internal card will render at 72s is taking 104s on a card on the Cluster.
Is this normal? Thanks for any advice!

Could be problem of splitting PCI-E slots speed so GPUs on that cluster work on 1x-2x PCI-E speed on MB since all 4 share single PCI-E slot.

Cluster has PCIe gen2 x1 host card, so that's where the hit comes from. However it should not be 50%. Could You give us more details on Your build?
