Hi, I'm finding strange rendering Octane with 2 cards in SLI, I have two video cards Gtx560 Ti Amp connected in SLI, but when I added the two plates, the program slows down when I move the camera, and when I leave with only one card, it is fast, why is that? with the two plates was to be very fast.

Octane does not support SLI.
Disable SLI.

octane (or cuda to be specific) just doesn't need sli. sli is for games only. if you disable sli in the driver settings, you can use as many cards as you like, and the performance of octane is the whole sum of all cards, even without sli...

Actually I had not paid attention to it, the configuration of the program has a warning about this, you have to disable SLI in driver.Estou surprised at the result, it was incredibly fast.
