I have 3 computers which have a quadro 1700, 3500 and 4000 in them. I have downloaded the latest drivers for all, but it doesn’t work! 1700 - Is found and activated in the “Select OpenCL devices for V-Ray RT GPU” When I submit a job for DR vray rt server just says waiting for command… then vray sta…

I have found drivers released in April that have CUDA 4.0, I will try these as the latest drivers have CUDA 4.1.

Its all working :slight_smile: I had 275.36-Quadro-winxp-64bit-international-whql installed. I installed 270.61-Quadro-winxp-64bit-international-whql and it is all working fine for all 3 cards. Thanks for the help. I guess it is down to the CUDA version being different?

I still seem to be having issues with this, using distributed rendering and the GPU. I hit render and I have excluded my own PC from the rendering. I have set the render to be only 500 samples, I hit render and on the render slave takes ages to start actually doing anything it says new data index is…

Also tried to render a scene on the Quadro 4000 via back burner and it said new data index is… and it wouldn’t start rendering at all. The render window started but did nothing. I think I made it fall over as the scene was quite heavy, see attached the scene I tried to render. [Test CPU 001.jpg]

Any suggestions on this? I also sent the job to the CPU using RT as a production renderer, and it just hangs saying rendering image. The RT server says preparing ray server. It seems scenes like the one above just cant be rendered using RT.

In active shade mode, it starts rendering pretty quickly, but using RT as a production renderer just seems to hang.

Make sure you close the ActiveShade window first. I thought this was fixed for V-Ray 2.10 though. Best regards, Vlado

Yeah I have done that, I have even restarted PC and just sent the job straight away to backburner and rendered locally and it just hangs. Is it possible the scene size is just too large?

Could you please try to install older nVidia drivers (form March in example) and let us know if the problem persist.
