I can add one Xpander (with 2 GTX480) to each PCIe x1 expansion slot
and keep my GTX260 in PCIe x16... ????
and Octane benefit of all cards?

PCIe x 8 slots, not PCIe x1 ! This has to be confirmed, but it is written.Connect as many Xpanders as you have available PCIe x 8 slots in the host computer
I'm not sure if it is the PCIe transfer speed that is the bottleneck. According to the specs, PCIe x16 1.0 has a transfer rate of 4 GB/s. That means that 290 MB should transfer in < 1 sec. PCIe 2.0 doubles the transfer rate (to 8 GB/s for x16).ROUBAL wrote: If you consider that the tested scene weights only 290MB, on a PCIe x 16 (even if it is a 1.0) the loading time(so, the transfer speed of the PCIe link) seems to be a very critical factor ! I doubt that PCIe x 1 are usable.
do you mean the loading/voxelising or the actual upload to the GPU when you click on the meshnode the first time ?ROUBAL wrote:What about animations ? Currently, frames on a slight scene are loaded in more than 2 minutes each, not only the first one. Is it the necessary time for Octane to update the geometry ? Can't it be reduced ?
