Skyrim deployed its own d3dcompile dll that nullifies shaders compilation, so you either have to load the one in C:\Windows\System32|SysWow64 or use prebuilt.
I use prebuilt
Why does CreateDeviceObjects return a bool if the NewFrame doesn't ?
Added the return parameter cause CreateDeviceObjects can fail.
It did fail on DX11 with feature level to 9.
Found on sanctum2, returning 0 in XPending & XEventsQueued make the SDL do something else than polling events and makes lag the event loop.
Now the event loop returns 0 when there are no more events.
If you really want to use d3dcompile, then I think its better to find the most recent d3dcompile you have on your computer and load its D3DCompile function.
This process is now automatically handled. Just define the right Preprocessor.
