NVENC Session count


I am confused about the number of concurrent sessions that can be run with NVENC. I have multiple Titan GPUs in a system, but I am always able to only run 2 encoding sessions.

Is this right? Why can’t I run 2 sessions per GPU?

As far as I can remember, only “professional cards” allow more that 2 sessions.

We bought some M4000/M6000 cards to get over this limit.
