Multi GPU Support

[hsz]

I was wondering if Vray take advantage of multiple GPU cards like Redshift does? I'm planning in getting 3 GTX 980 TI.

Yes, V-Ray works fine on multiple GPUs and scales pretty much linearly.

Best regards,

Awesome glad to hear that.

hsz, I don´t know, what You plan to render with the supercards..
Did You checked if all You whant to archive is possible with vray GPU?
I´ve the 980 TI Strix here too and spend inclusive bigger power supply, case more than 1000€ (for one card!).
...in hope to get faster renderings, without the little minifarm.
But there are so many differences (restrictions) between CPU and GPU...
...that I can say, not one project I made in the last month, became part of the GPU power!
Inclusive the new "production render engine" in 3.3.
So for me, the GPU thing is realy frustrating in that moment!

May be, that other useres see that completely other...would be interresting....

cheers, Jörg

It will be really helpful if you can send some of the scenes you have tested with to blagovest.taskov@chaosgroup.com (they will be used for dev purposes only, we can sign NDA if necessary) , so I can check what the problems were (and eventually fix them). RT GPU is used by many clients, but having more of the scenes that don't look quite right helps to prioritize the dev tasks.

Thanks,
Blago.
