Cubix PCIe extenders are connected via a single PCIe slot of the source computer and therefore all GPUs installed share the bandwidth of this slot. In addition, in the case of MacPro 2010 this is a PCIe 2.0 connection, not PCIe 3.0, which limits bandwidth even further. Therefore if you are observing low rendering speed, PCIe throughput may be a limiting factor, not computational power.

It is not quite clear from your description what you mean by ‘jumpy image’ and what exactly is the problem you are experiencing.

Please contact Neat Video support on this issue and describe the problem in a bit more details. Hope we will be able to help.

Thank you,
Tim
