I get about 28-31 out of my 680. Does anyone have a common
explanation for that?

Hey Mirko I ran your script and I got 50.7 fps...
But then I remembered I have my displays plugged in to my
470.. hahaha.
Don't ask why, but when using AE with the displays
plugged into the Ti, AE does not like it and disables
GPU for calculations...
Pffff.

Hey Tim
Would you be able to take 2 minutes of your tmie and
run this ol python script for SI with your titan?
I'm getting weird results with an 780 in my home
system outperforming titan a lot... well here is copy
paste from forum if you are able to check it out as
well.. thanks!:
itan: ~170 fps
780: ~245 fps
Go figure :)
But I'm suspecting something weird with my titan
system for some time will have to test further but
would be great if anyone with titan as well could run
it too?
This old python script:
Application.CreatePrim("Cube", "MeshSurface", "", "")
Application.SetValue("cube.polymsh.geom.subdivu",
831, "")
Application.SetValue("cube.polymsh.geom.subdivv",
800, "")
Application.SetValue("cube.polymsh.geom.subdivbase",
800, "")
Application.SetValue("Camera.camvis.refreshrate",
True, "")
Application.SetDisplayMode("Camera", "shaded")
Application.DeselectAll()
Application.SetValue("PlayControl.Out", 5000, "")
Application.DeselectAll()
Application.GetPrim("Null", "", "", "")
Application.SelectObj("Camera_Root", "", "")
Application.CopyPaste("Camera_Root", "", "null", 1)
Application.SelectObj("null", "", "")
Application.SaveKey("null.kine.local.rotx,null.kine.local.roty,null.kine.local.rotz",
1, "", "", "", "", "")
Application.SetValue("PlayControl.Key", 5000, "")
Application.SetValue("PlayControl.Current", 5000, "")
Application.Rotate("", 0, 8000, 0, "siAbsolute",
"siPivot", "siObj", "siY", "", "", "", "", "", "",
"", 0, "")
Application.SaveKey("null.kine.local.rotx,null.kine.local.roty,null.kine.local.rotz",
5000, "", "", "", "", "")
Application.FirstFrame()
Just paste in python script run and hit play.
Thakns!

We've been testing 1 Titan vs. 3 and so far, the
speed increase of the triple-Titan box is holding
at about 2.45x. In an email exchange (or maybe it
was on the forums, can't recall) it was mentioned
that on the topic parallelization, Pixar had
determined that even for them, 4 units together
(of whatever, not necessarily Titans) was the max
they could really go before it started to cost
more money than it was worth. In our case, I'm
thinking 3 might be our max, based on some nerdy
mathematics by one of our IT guys analyzing
render times per shot, per frame,
hardware/software costs, rack space used, etc.
But hey, Redshift aside, the Titan in my
workstation is doing wonders for my viewport
performance in Soft. I had a 58M, 2500-item model
derived from a CAD file the other day, and this
thing was letting me tumble around it at ~15fps
in Shaded mode. That ain't shabby!

There was a discussion on the RS forums about
it. I don't recall the numbers, though. I
don't think the speed of the PCIe slot made a
huge difference. It's really all about the
speed of the card.
Also, although it doesn't load the entire scene
into your card's memory, the more memory your
card has, the better it is.
But overall, for the type of work I'm mainly
doing these days, it's extremely fast. In fact,
it's so fast that I was finding the bottleneck
was the time taken to export the mesh to
Redshift, not rendering. Redshift has a proxy
system like Vray & Arnold, but you have to
manually create proxies per object & my scene
had hundreds and hundreds of objects, so I
didn't have time to create them. Therefore, it
was creating a renderable mesh per frame - so on
a frame that took 28 seconds to render, 20
seconds was spent exporting the mesh and 8
seconds were spent on rendering. But again,
it's a beta and they're continuing to improve
things like the proxy system.
Once I'm caught up I'm hoping to try rendering
the classroom scene and see how it does.
