I am using 2x GeForce GTX 770 (SLI) to render in Octane Plugin for 3ds Max

------------
Every project I render usually looks something like this. It starts off slow, then gets really fast, then gets extremely slow. It doesn't matter if i have a simple scene or a very complex scene.

Is this because the grapics cards are running out of memory?
Is it because I don't have a correct setting right?
Is this due because backburner has issues with Octane?

Has anyone else had this problem?

(see attached image for the times I am getting when rendering most all of my projects)

i think octane hates sli

coilbook is right. Never have your cards in SLI when rendering with Octane. Not exactly sure why it would cause this problem, but that's more than likely the case.

So far so good. I disabled SLI, and its rendering more consistently. Doesn't make sense to me, but it worked (so far). Octane must have a bug dealing with SLI.

I'll keep chopping at it, and testing with other scenes.

Octane doesn't "deal" with SLI and doesn't use it. It just sees multiple devices/GPUs via the CUDA API and uses them totally independent of each other.
