Unfortunaly, I do not MSFF> have a booktree board to test capture performance. CPU utilisation is down by 3-5% (of the total available) on my AMD compared to my optimisation attempt. Usage seems to be less peaky too. With motion estimation off I could probably record two streams at once in real time (CPU usage for one is around 40% and steady, unoptimised it is around 70% and peaky).
