Minimal rendering help from GPU

I am using MSP 12 (64-bit) to render a VHS capture to progressive-scan DVD, which should be pretty fast. Problem is, it doesn't seem to go any faster with GPU acceleration.

I have watched the CPU and GPU loads, and the CPU is pegged out solid at 90-100% during rendering, but the GPU is only spiking up to 60% or so every few seconds, with 0% in between.

Is this all MSP 12 will use the GPU? It's barely touching it, and the rendering speed doesn't appear to be any different with or without GPU acceleration enabled; all the work seems to be done by the CPU regardless of the setting.

What gives?
