Can't wait for some Octane benchmarks! :) btw. how come this thread was moved to a non-public section of the forums?

CUDA error on device 0, cannot use this device for rendering - and that's it ;)

it was just moved to Public Forums ยป Resources and Sharing because it would fit better. but wasn't aware, that this is not really public - moved it back, thanks...

from behind the newzealandian wall of silence

As a citizen I wish to distance myself from this foreign company :P
Seriously though, I am actually hoping they send someone out to do the business management role.
Or perhaps I should just move to Auckland. I can get paid for my time then. :lol:

Nice benchmarks. I see a GTX680 is about 3x faster than a GTX460, so the GTX660 ought to be 2x faster.
So graphics card performance doubles in 2 years....
In 2014 people with 8x GTX880 will be rendering the same scene I wait 24 mins for in 30 secs.
I guess speeds will top out like they did for CPU...maybe after another couple of generations...possibly down to 7.5 secs which is 3mins rendering per sec of animation. If you are super serious with 3 such rigs, 1 min 8-)
Imagine that though 7.5 secs! hardly enough time for 2 slurps of coffee :roll: :cry:

You haven't had any problems running it at a 165 mHz overclock?

I hope you get a chance to use it in Octane soon...

because there isn't anything else i could do with the card, i tried +300 - resulting in another 5% more; means +15% or a half gtx 560 more power than on stock clock :D
at +400 it dropped out...

An extra 300 mHz is a lot. That's encouraging.

It's funny... I almost never play games anymore, but I've never more felt a need to get the latest graphics card hardware.

But not till I hear a bit from Refractive regarding this issue.

Seeing the DirectX11 compute shader fluid simulation results, maybe it will scream when everything is updated.

some news: found this http://developer.nvidia.com/sites/defau ... /glass.exe (thanks to the 3dcenter.org forum)
it renders a scene with 3 glasses using cuda based raytracing, thus should be at least a bit more "real world":

test was glass.exe -d=3840x2560 -B=15x60
(means image of 3840x2560px dimension, 15sec warmup, 60 frames rendered, no display)
driver version 301.10

Code: Select all
gtx 560 ti @ 822:   1.29272 fps / 46.4139 sec
gtx 570    @ 732:   1.91363 fps / 31.3541 sec
gtx 580    @ 772:   2.28240 fps / 26.2881 sec
gtx 680    @ std:   2.38455 fps / 25.1625 sec
oc'ed:
gtx 580    @ 850:   2.48827 fps / 24.1132 sec
gtx 680    + 300:   2.81746 fps / 21.2958 sec

somewhat less promising, still hard to judge, as this thing seems to be very old...

I just got 2 GTX 680's and installed them but for some reason they are not working with Octane Standalone and Octane plugin for Max. The render progress window does not go anywhere and the GPU's are not being used at all. I am monitoring them with the EVGA Precsion X that came with the cards. I have NVIDIA Graphics Driver 300.83 installed which is what came with the GPU's.

In Octane Standalone it shows that both cuda devices failed. Is this maybe because these are CUDA 3.0 devices and the 580's were 2.0???

I was super excited to try these out. Hope to get them working soon so I can report the performance results with Octane. Has anyone else successfully rendered with Octane on GTX 680's??

Thanks!

Hi, it is not possible atm., octane needs to rebuild against Cuda Toolkit 4.2 which is in Release Candidate status.
I think the next version (beta 2.6) is build with Cuda Toolkit 4.2.

Cheers, mib.

Oh man, that is a real disappointment! Putting the GTX 580's back in for the meantime then! ;-(
