I have been experimenting with with pmode on my 5950X platform.

I typically encode in Slow, Slower or Very Slow.

For all 4K encodes, the CPU will run at 90+% utilization and pmode causes encodes to take longer.

For BD encodes at Slow or Slower, the encodes take longer with pmode.

For BD encodes at Very Slow, pmode does reduce encode time - in one example an encode took 13 hours at Very Slow and 10 hours at Very Slow with pmode. It also seems to increase CPU utilization around 20% (from mid 40% to mid 60%).

I've only tested on 3 files and while two showed slightly smaller output file size, one showed a significant output size reduction (4247 MB without pmode and 3474 MB with pmode).

Nothing in documentation or what I've read here, lead me to expect this result....wondering if there are any thoughts/comments on this result..??
