Multi GPU test.

[Karonte]

Hi Vlado i have a question:
I try Vray GPU in a big machine with 2 graphic cad indide + 1 cubix ( 2 video card)+1 cubix ( 2 video card) : total 6 GPU.

First of all i try only 1 card inside the pc and the statistics were: 900,000 Kpath /s. (I see one card full work 100%).

Then i try to enable the other one (5 card) and i see always 900,000 Kpath/s. ( I see that 6 GPU work al 20% each and not at 100%).

How it's possibile? i made mistakes?

sorry for my english.

Does it work if you plug the GPUs directly on the motherboard? I'm not sure how Cubix works, but we have tried up to four GPUs in one machine plugged directly on the motherboard and everything seemed fine.

You can try to increase the bundle size/rays per pixel a bit and see if it helps, but this may take up more GPU RAM.

Best regards,
