Is my gtx 260 graphic card useful for Iray rendering?

in Technical Help (nuts n bolts)

I have a releatively old graphic card, a GeForce GTX 260, it appears in render devices but when I try to render without CPU the render is aborted before the first iteration and I'm left with an empty canvas, I wonder if I can use it for rendering at all? something like a driver update or spcefic program to install perhaps?

    To be honest with you, you won't have much fun using Iray with that card. 

    If you are really wanna use Iray you should get yourself a newer Nvidia card - something like a 660ti or higher.

    I do have a 970 and my render times are pretty good.

    And a AMD card won't work right - Iray is developed by Nvidia.

    it's true that my card is a very old model but the thing I'm wondering about is: would it be able to render since it appeard on the list of devices? or any card will appear there even if it's not capable of rendering.

    I guess any card appears in the list. Not sure about AMD cards tho.

    Your card can render things in Iray, but I guess it will reach its limits very fast.

    It looks like it's only a 1 GB card with only 192 cuda cores.

    If you do manage to get a scene to fit within 1 GB, then the 192 cores will take forever to process and render the scene anyway.

    it has less than 1GB, around 800mb, but I'm rendering only one figure is that more than 800MB? the fact that the render don't start leaves me wondering how slow is it comparing to my core 2 duo E7400. only if I could have a test to compare...

    A CPU is in Iray always slower than a Nvidia GPU, at least one of the newer Nvidia cards.

    To make a long story short - if you really want to do renderings in Iray you should consider upgrading your graphics card.

    A 260 shouldn't just 'drop' at the start of a render...look in the log file and see what it is saying aobut the card and the reasons it's dropping (Help > Troubleshooting > View Log...).

    here is what I get in the log

    just a simple cube to render, maybe I should update my driver cool

    You need 4GB of RAM on your GPU to utilize it in Iray.
