D3D11CreateDeviceAndSwapChain fails with 887a0001
See the question and my original answer on StackOverflowIf you debug your program, you should see this in the output:
DXGI ERROR: CreateDXGIFactory cannot be called from DllMain. [ MISCELLANEOUS ERROR #76: ]
This is expected as explained here: DXGI responses from DLLMain (D3D11CreateDeviceAndSwapChain
will implicitly create a DXGI factory)
If your app's DllMain function creates a DXGI factory, DXGI returns an error code.
So, you must not call this from DllMain
(this is anynay a very special place where some black magic voodoo happens.)
