Hey everybody!
I posted on this issue before here https://forum.blackmagicdesign.com/viewtopic.php?f=21&t=84529, which was full of good and bad information. But I since have performed much more tests with Resolve Studio 15 on Windows 10.
My issue is this: I am using H.265/HEVC clips in a simple test timeline using a forward and a reverse clip, applied a bit of global and selective grading, with lens distortion and rotation for good measure.
In that test, the VEGA64 performance (export speed and playback speed) sits between a GTX1060 and an old GTX970. The most shocking part is that the task manager reports a 10% activity from the VEGA card (I tested latest and older drivers), while a 960, 970, 1060, 1070 all seem to use between 50 and 100% of their power according to the task manager.
It looks like the VEGA64 has unused power just doing nothing. The CPU (Ryzen 1700X) is at 95%, while with a 1060 for example the CPU is a 60% usage.
On my system, the 1070 manages to be faster than the 1060, so I don't think I am bottlenecking much.
What's the deal here?
Is this normal?
Puget systems reports here: https://www.pugetsystems.com/labs/artic ... ance-1238/ that the VEGA64 has better performance than a 1080TI using H.265 clips and some grading. I tried auto settings and manually selecting the card and openCL settings. No difference.
There must be something wrong here? But I don't see why. The system is a fresh install as well.
