ok yes, someone recommended mode=5 for source filters however looks like not this one.

if multi-threading is "out" when using NV then multi-core boxes like my 4-core effectively become single-core boxes inside avisynth... hence it must be swings and roundabouts for overall speed.

in this specific case there is no problem, since not much is being done and x264 multi-threads anyway - however if there's a lot of processing to be done inside avisynth then NV's single-threading requirement may end being a "chokepoint" for overall performance.

unless there's a way around it I don't know of (i'd thought to use MT, the 1st line of a script had to contain a setMTmode).

oh well, at least we know. thanks.
