AMD Radeon R9 M390 Driver issues on Windows 10
(Late 2015 27-inch iMac i5 3.2GHz 1TB SSD)
I've installed Windows 10 using the updated boot camp software and drivers from Apple. I still get error "No AMD graphics driver installed, or the AMD driver is not functioning properly. Please install the AMD driver appropriate for your AMD hardware.".
I've tried downloading various "updated" drivers from AMD and Apple, but get no results, still the errors of the graphics card not found/ driver not found. I've been trying for months to resolve this issue, and have gotten nowhere with any of the three parties Tech support. Microsoft and Apple say it's the hardware manufacturers responsibility, while AMD says it's an Apple issue. No one seems to want to take responsibility and I'm so frustrated at this point.
Has anyone had a successful workaround to this issue?
