I'm just doing some testing now with the iMacPro definition to see if the darkwakes resolve themselves now. With iMac19,1 the system will go to sleep but once it wakes up, it'll stay awake. I'm also running the latest Public beta of Catalina but this issue was present in 10.14.5 after switching to iMac19,1 from iMac18,3.Yes, I currently have IGPU disabled. Some people have IGPU enabled with iMacPro1,1 but I haven't personally tried that yet.
Obviously, we lose Quick Sync with IGPU disabled, but the changes in the way graphics is handled in macOS 10.14.5 pretty much negate any disadvantages to having Quick Sync disabled. As far as I can tell, h.264 and HEVC are handled perfectly now. I use the Sony Food Fizzle demo video in QuickTime as a test. This video will bring Skylake and older systems to its knees but it's buttery smooth with iMacPro1,1 system definition in 10.14.5.
As for encoding, all those who have been using iMacPro1,1 system definition with FCPX seem to have no complaints. There are a few users who have been experiencing slow GPU performance, but that's a separate issue.
The darkwakes was probably the primary reason that triggered me to try iMacPro1,1 and it's been a revelation.
Also as you mentioned I can confirm the processor now idles at 800Mhz instead of 1.3Ghz.
I have been able to boot with and without iGPU enabled. It would be interesting to see if I could get Quicksync working along with DRM...
Is there anyway to test DRM content in Safari? I don't use Netflix
