no change with Geforce Driver 365.19. All results same as I reported before.

@Ton Roosendaal (ton)
But the developer is silent. I for one, have the 2 GPUs and some free time. I could make some testing if there was something I could test on user level to help...

@Alicia
GPU rendering is definitely the future. Just have a look at what Octanerender are doing. Otoy.com.

There are opinions that SLI is not good for rendering and that makes sens to me but I have no direct prove, I would try to inactivate SLI
I have 2 gpu and BMW renders 42 s non SLI

What you mean by very quickly? How many samples? Which light path tracing?

Preview render is not snappy at all.
4 samples take 10.83 s on 980Ti and 3.85 s on 980 and 3.72 s on both.

I did also fan speed test controling 980Ti by ASUS Tweak. I do not see performance differance when speeding up fans of Ti. By default if is lower speed and much higher temp than 980.
980 35 C idle
980Ti approx 50 C idle

Hi Guys
I just installed 980 Ti an got disappointed as may. Then I found this forum.
I would like to share what I tested about the famous tile size and render speed theory
