Just installed Blackmagic Intensity IO on a brand new fast build. Disks are flying at 400Mbps (or an unbelievable 2000Mbps on M.2 PCIe SSD!) and its a hex core at 4.4Ghz with 32Gb 2666Mhz RAM. Blackmagic Intensity card monitor output works well in HD and on UHD footage used within an HD project. However if I switch to an UHD project in Avid it all gets unusably jittery within Avid and on the BM output. If I disable the hardware via the timeline button Avid copes fine with the 4k footage.
Anyone have any ideas here - if its not Avid it could be a PCIe bottleneck or a BM issue I guess? But I was sold a 4k card!
Thanks
