I am using a W8100 card on Windows 10 64 bit with latest Windows updates and AMD 17.Q1 driver.
So far, it has been impossible to use 10 bit with Adobe PS CC. At this moment I do not know if the problem is from AMD or Adobe, but no company acknowledges the issue.
See some links:
Problems range from liquify not working and cyan cast on gray images, to not being able to open RAW files.
As soon as I turn off 10 bit support on the AMD FirePro settings, all these problems are gone; of course, no 10 bit rendering on the Eizo monitor.
Any acknowledgment would be appreciated along with an ETA.
