Hello, i'm sorry for my english.
I want to say when in octane can see all 336 cuda cores and not 224!
PS. I have the cuda toolkit 3.2, but in octane show cuda driver version 3.0.
When i will see all 336 cuda cores?

Octane is compiled for/with cuda 3.1, so the next 2.36 or 2.37 intermediate release get the benefits from 3.2.
Then also a new demo is comming out.

Octane 1.022b and 1.023 v5 were build with CUDA 3.0. We are currently trying to make Octane run with CUDA 3.2, but ran into some performance problems with it in some situations. -> We can't say, when Octane will use CUDA 3.2 to support compute model 2.1. I'm sure, we will eventually find a solution, but it might take some time and I can't really say, when that will be.

We have a version of octane running with cuda 3.2 since last week, but we are experiencing some issues with multi-GPU performance due to changes in the CUDA toolkit between 3.0 and 3.2 which we're fixing currently.

If I understood correctly,
as for a GTX460,
if you have cuda toolkit 3.0 installed, you get 336 cuda cores rendering.
if you have cuda toolkit 3.2 installed, octane will run on only 224 cores? ...and render significantly slower?
So It´s better to keep the old 3.0 drivers - and wait until there is a bugfix for octane?
Is that correct?

No.
We won't get 336 cores until we have 3.2 CUDA installed and Octane is built on it.
Keep the drivers that work for you, until 3.2 CUDA version of Octane comes out.

Yeah, it's best to install the same versions as we recommend with the release.cornel wrote:If I understood correctly,

Forward compatibility is not always guaranteed.

you need to wait becouse Only CUDA Toolkit 3.2 is officially full support GTX460cornel wrote:Reason I asked is, those two 460`s I´ve ordered are about to arrive soon.
So I already try to prepare myself.
Thanks for that hint, radiance!
i tryed with 3.0 ver with 3.1 but only what i see is 224 cores in octane
even i didt can install cuda 3.0-3.1 its say that cant find any device supporting cuda
we need to wait...
