I have recently installed an Nvidia Tesla C2050 to run along side my Nvidia Quadro 3800. Since installing the new Tesla card, Whenever I launch a V Ray RT render using OpenCL (single kernel) my RT Dos render window/log crashes and nothing happens in my render view. Just wondering if anyone knows h…

Which are the driver versions that you installed for the Tesla card? Other than that, a Tesla card is not particularly faster than a GeForce card, but is more reliable and has more video memory. Best regards, Vlado

Thankyou for your feedback, I have tried 276.14 and 275.65. Is there a place were V-Ray RT stores a log that I can show you guys? System is: Windows 7 64bit Service Pack 1 16gb Ram 2x Xeon E5530 2.40GHz Quadro FX 3800 Tesla C2050 Maya 2012 V-Ray For Maya 2.00.04

Thanks for the screenshot - it seems to be because the two graphics cards have different architectures - the Tesla is a Fermi card, while the Quadro is not. You can try disabling the Quadro card from the V-Ray RT OpenCL device selector utility from the Start menu and see if this solves the problem. …

Thankyou for all your feedback. I have noticed that V-Ray for Maya does not have a “OpenCL device selector utility” In the start menu but V-Ray for Max does. If I use the V-Ray for Max selector will this also work for V-Ray for Maya also? Please see the attached image. On a more general note, If…

Hi, You can manually choose the device by defining an environment variable VRAY_OPENCL_DEVICE=1 (or the number of the device you want to use). You can specify many devices using commas. On the other questions: 1. VRay RT GPU is not using rasterization, but raytracing and thus is not using the GP…
