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.
