Hello Guys
I have a technical question which is closely related to vray.
I purchased 3x970 Gtx cards last year because I thought that vray rt render is going to be faster with 3 gpu cards instead of one cpu. (based on all the tech videos on the net) I have done loads of testing after I had a few forum conversation how to make it work.
Cuda render works fine now with the latest nightly build. However I am not satisfied with the speed of it. Its probably my fault that I was fooled by the gpu render tech demos on youtube and all the articles about how much faster gpu renders will be and "the future of rendering is gpu" etc.. or I couldn't afford a 3000 dollar Titan, I could only buy nvidia 970s.
I might have done something wrong, despite of the fact that I tested lot of scenes, but its always kinda the same speed for me with the 3 gpu cards like when Im using my cpu. (i7 - 5930k) The problem is the noise in the shadow areas, they never seem to go away only in the most simple scenes. I've got the an almost final image in a few sec then I have to wait 10 minutes for the noise level to go down.
Its not only the speed of course, the stability of the system and the software was far from cpu render as well.
Vlado here once told me that the time of cpu render is far from over, and I beginning to believe that now. So I've decided that instead of a 3 way SLI I now change it to a dual CPU system with xeons. I've done an extensive research on dual xeon systems, I've already put together an affordable dual cpu system as well, I just want to hear what you guys think of this idea before purchase. They say more cores with slightly lower frequency is better for rendering that is why xeon cpu is a good choice.
Please if anybody here has some experience or advice on this subject dont hesitate to share it, and I know it might be a noob topic so you dont need to remind me about that
Thanks very much!
