Those are some impressive render times!

Hey guys,
Thanks for the great responses. I think I've responded to everyone who sent
an alpha request, but if you think I missed you, please shoot me an email to
remind me :)
Also, I wanted to share some render times as we ran some more tests this
afternoon comparing the GTX 470, GTX 670 and GTX Titan (which we actually
received after the announcement went out) for the scenes we posted.
Some of this info is also on our announcement thread on CGTalk
(http://forums.cgsociety.org/showthread.php?f=59&t=1098062).
Gargoyle 1280x720 (jp_studio_icp_1280.png)
GTX 470: 35 seconds
GTX 670: 27 seconds
GTX Titan: 17 seconds
Car 1024x683 (mazda_1024.png)
GTX 470: 75 seconds
GTX 670: 65 seconds
GTX Titan: 39 seconds
Evermotion Living Room 1200x1000 (AI_V8_S10_1200.png)
GTX 470: 155 seconds
GTX 670: 123 seconds
GTX Titan: 77 seconds
Classroom 1024x512 (classroom.png)
GTX 470: 129 seconds - ok I exaggerated a bit when I said 2 minutes :)
GTX 670: 96 seconds
GTX Titan: 49 seconds
Please also bear in mind that we're still just in alpha and constantly
improving performance. We're kind of obsessed with speed :)

Exactly! This is VERY interesting. Hope I can test (sent request
already) :)

Yes - I'll try to make a video of that if I can get set up correctly for
it.
Note that this is 2 mins on a GTX 470 which is nothing special in terms of
GPUs. You can expect significantly better times with a GTX 580 for example.
I don't have official times for that card, but I'd guess under 1.5 minutes.
These kinds of times really underscore the power of biased rendering.
When you need to reduce noise, you have a lot more options than "let's just
throw a ton more samples at the whole thing".

The classroom is really 2min render ?
Congrats to you, sending a request :)

congrats to you and your team! i was wondering when we would see/hear
about your work.
it would be great to see a video demonstration of redshift in softimage.

Hello folks,
In March of last year, 2 colleagues and I left our jobs as software
developers in the games industry to form our own company - Redshift.
Our goal was to apply our experience with graphics hardware to the
problem of "offline" rendering.
Artists friends had been asking us for years why Mental Ray and other
renderers were not taking advantage of the GPU.
As the ideas bounced around in our heads, we figured we'd take a crack
at it. As it turns out, it's really freakin' hard, but not impossible!
Today, we're very excited to announce the official launch of Redshift
v0.1 alpha, to our knowledge, the world's first fully GPU-accelerated biased
renderer.
Redshift supports multiple GI solutions: Brute-Force GI, Irradiance
Caching (aka Final Gather), Irradiance Point Cloud (aka Light Cache) and
Photon Mapping (GI and Caustics).
All are fully GPU-accelerated and perform many times faster than similar
CPU-based offerings.
A problem that plagues many GPU renderers on the market is that they are
limited by the available VRAM on the graphics card (and most systems have
significantly less VRAM than main memory). Redshift addresses this by using
an out-of-core architecture for geometry and textures allowing you to render
scenes with tens of millions of polygons and gigabytes of textures with
off-the-shelf, inexpensive hardware.
Redshift currently integrates directly with Softimage 2011 through 2013
and Maya 2011 through 2013 on Windows XP or higher. 3ds Max support is in
development. To run Redshift, you'll need an NVidia graphics card
supporting compute 1.2 or higher with 1GB VRAM or more.
You can check out our website http://www.redshift3d.com for more info.
We're currently in closed alpha, and looking to find some interested
alpha testers on this list.
Our goals for alpha are to shake out bugs and gather feedback from users
to help focus our development efforts.
If you're interested in taking Redshift for a spin, drop me an email at
[email protected].

And the classroom scene from the "Octane Render" thread from a couple
weeks ago. 2 minutes on a single GeForce GTX 470.

I'd also like to thank all of those on this list who've answered my
various questions about the XSI SDK. Your help has made our integration of
Redshift with Softimage very strong.
Cheers!
Nicolas
