...and how is the speed, now that you've been using v12 for a few days now? How does your speed compare to v11? Is it noticeable, or does one need specific hardware?
The test case was the simple Nature.mpg as evaluated here in the pdf.
http://forum.cyberlink.com/forum/posts/list/25826.page#140632 The test case makes it easier to understand load on various GPU's/CPU's and may provide some performance insight.
GTX580, 320.49 driver
QS, 9.17.10.2932 driver
CPU, i7-3770, Intel HD4000 GPU
Win7 64bit pro, 16GB
Below are some relative ratio's on elapsed time.
For a H.264, 1920x1080 16Mbps output
QS, PD11 1.5, PD12 1.0 (if PD12 took 1 unit of time, PD11 took 1.5 units)
CPU, PD11 2.1, PD12 1.0
GTX580, PD11 1.0, PD12 1.0
For a MPEG2, 1920x1080, 25Mbps
QS, PD11 1.0, PD12 1.0
CPU, PD11 1.1, PD12 1.0
GTX580, PD11 1.0, PD12 1.0
On my system it depends very heavily on how one has set, for instance OpenCL technology in the preferences, ticked or unticked can result in significant changes, 2-3X and varies with what hardware is doing the encoding.
From what I have seen, when configured correctly, PD12 is equal to or better than PD11 from a encode elapsed time point of view. Benefit appears to be a strong function of output format.
