I upgraded to Windows 10 Pro x64 from Windows 8.1 Pro and PowerDirector 12 works correctly on my system, apart from having no hardware accelerated video output from my AMD HD 7750 discrete graphics card. Accelerated effects do seem to function ok, so I'm guessing that Open CL works fine, as it does in Lightroom 6 and DXO Optics Pro.
If I switch the BIOS over to use internal graphics from the i5 4590 CPU, then Intel Quick Sync hardware acceleration is usable for video encoding. It's a shame that there is no switch within PD12 (or 13) as there is in Handbrake, to use Quick Sync even when another discrete graphics card is primary.
I have tried the trial version of PD13 and the situation regarding encoding acceleration is the same, though I don't know if the latest PD13 patch addresses this. If upgrading to 13 changed this, I guess I would pay, but until this is confirmed I will sit and wait, outputing all my videos using SVRT to .mts files and then putting them through Handbrake using Quick Sync for more compressed MP4s.
AMD driver is 15.7.1 x64
PS Just checked my HP Pavilion laptop, which came with PD12 and uses Intel HD 4400 graphics and this was upgraded from Windows 8.1 to Windows 10 Home (x64) and PD12 works without any issues.
