New Mac Pro (2013) D300/D500/D700 do not work in Windows 10. Don't upgrade unless you're okay with using the basic (non-3D) drivers.
I've tried reinstalling the Boot Camp drivers as well as the Omega and latest Windows 10 drivers from AMD to no avail: they all fail with a message in Device Manager: Code 43
The funny thing is that just before all this, I was running the tech preview and it worked great with whatever driver I had (it was the Omega drivers when I upgraded, but I'm not sure if Windows had updated them too during the upgrade).
