The question of using or not using Hardware Acceleration has come up at every release of Powerdirector.
If you read what Cyberlink says about their test platform, you get a good idea of the condition they tested.

There are an unlimited variation in computer configuration. Each one provides a different experience.
On my computer, Powerdirector 9, PD 11 and PD 12 all perform as expected. That is My computer. Other people have different computer setups.
Everybody's experience varies.
In this forum are some long time users and posters that will tell you they do not experience the problems posted in the forum.
That is why we are answering the posts. We know what works, and in some cases the cause of why it does not work.
Hardware Acceleration (HA) is the video card, in that computer and the Video Driver installed on that platform.
On some systems HA works well, on some systems it does not.
It does work on my current setup. I still don't use it much. I do not like having to render a project twice.
It is once if HA works, Twice, second time no HA if it does not.
So I usually don't use HA, the amount of time to render is not that much greater.
The exception to that rule is SVRT, if SVRT is active, I do use it.
