Boot Camp DirectX driver problems on Mac Pro 2013

Since months (since the last Boot Camp driver update to be precise) I am encountering massive problems with Boot Camp on my Mac Pro Late 2013.

Applications would crash randomly returning the error

"DirectX function "Dx11Renderer::tryMap" failed with DXGI_ERROR_DEVICE_REMOVED ("The video card has been physically removed from the system, or a driver upgrade for the video card has occurred. "). GPU: "AMD FirePro D300 (FireGL V)", Driver: (15.301.2101-160209a-299468C). This error is usually caused by the graphics driver crashing; try installing the latest drivers. Also, make sure you have a supported graphics card with at least 2GB."

Of course I am using the latest driver that Boot Camp offers me to install and the GPU is not removed for obvious reasons. OS is Windows 10 with current updates installed.

Anyone else having this problem and knows about a solution?
