Setting up CUDA cores

[MR_MU53NDO]

i'm a bit new to the idea of CUDA cores, and after hearing that they can reduce rendering times considerably, i decided to download the toolkit from the nvida website. i've installed it, but 3ds max (3D modelling program) still appears to reject my gpu when i try rendering with it. i get this when using iRay Renderer:

IRAY 0.8 warn : ignoring unsupported lens shader type "max_base_GBuffer_lens"
IRAY 0.8 error: CUDA device 0: invalid device symbol
IRAY 0.8 error: CUDA error on device 0, cannot use this device for rendering
IRAY 0.8 error: rendering fragment failed on device 0
IRAY 0.8 error: CUDA device 0 failed during first frame, deactivating it and re-rendering now
IRAY 0.8 warn : ignoring unsupported lens shader type "max_base_GBuffer_lens"

i have an nvidia gtx 660Ti, with 3GB memory, so it should work fine.

Am i doing something stupidly wrong, or is there a different problem here?

Not 100% on this but have you downloaded the Cuda bits and bobs from Nvidia. I have no clue but believe you need the extra bits.

i downloaded the cuda toolkit, but not any of the documents that came with it.

I did look into this a little further (more so for curiosity) and I believe it should be part of the drivers (306.23) for example.

I will look a little more and see if I can find anything else.

Edit:

I assume you have this installed?

yes, that's correct. downloaded the win8/win7 desktop one

The only other thing to try is changing drivers and if that does not work, send the makers of 3DS Max an email.

Sorry I can't help further

okay. thanks for your help! there's probably something on the 3ds Max website about setting up graphics cards for rendering anyway. i'll check now

well that's a pain saw this on a different forum:

"apaprently the new GTX 600 series do not work right with 3ds max 2013 nor iRay (yet).

when they do...I hope the cards perform better then the 500 series...or even the 400 series… hearing they are not...but guess wait ...and wait...and wait.... and see. uggh."

Oh well... better wait for the next 3ds max update then
