Tried this with 3C. I switched JNPG to core 0 then core 1. I was over the moomnwhen I saw that my chronic snap line slide bys were nearly gone. Just the occasional very slight slide by. Then i came back down to earth when I realised FPS had fallen by 25/30 so the video display was nearly at a standstill. A real pity.
