Just updated all my CC apps and using Premiere CC 2014. Created simple output sequence and rendered it out in simple 1080i, H.264 Quicktime preset and only one CPU seems to be processing. Preferences are for CUDA processing as it's always been. Used to get almost faster than real-time rendering and saw 60 to 75% CPU utilization. This one took nearly 5 times real time to render.
Have dual processor Dell T7600, 32gigs, dual XEON 2.3GHz, Win7 Ultimate, NVidia Quadro 6000 (driver date 8-4-14, version 9.18.13.4066) Could Quadro driver be problem?
I am getting black screens occasionally when openning or shifting from media browser and/or Bridge back to Premiere.
Matrox MX02 for display monitor.
Seems to be OK today. All processors churning at about 70% for an H.264 1080P clip. Life's good. rg
