Our display configuration is the following:
Windows 10 Enterprise 1809 (Tweaked as of Dataton guide)
Asus WS X299 Sage
32 GB of ram
NVMe Samsung 970 Pro
AMD Pro WX9100
BlackMagic DeckLink 8K Pro
BlackMagic DeckLink Quad 2
Midi Controller APC40-MKII
After a week of testing we established that:
Using Windows 10 Enterprise LTSB 1607 Watchout Display shows the same error as @Jeff Miller (both with AMD 2017 Q4.1 and AMD 2018 Q4 drivers).
We installed Windows 10 Enterprise 1809 and AMD 2017 Q4.1 drivers and it kinda worked but with 4 parallel live input all of them was lagging and freezing (also pre-recorded videos)
We finally tried installing Windows 10 Enterprise 1809 and AMD 2018 Q4 drivers, it now works without quirks, WatchPoint now starts immediately and it doesn't freeze anymore (6 outputs 1920x1080@60, 4 SDI live input FullHD and 1 DVI live input 1080p, 1 NDI Input 1920x1080@60, 2 UHD Videos playing, HAP and H264).
We noticed performance boost setting these options in bios:
- Hyper-Threading: OFF
- C-States, P-States, Intel SpeedShift/SpeedStep: OFF
