The line: "ctx->PSGetSamplers(0, 1, &old.PSSampler);" will fail silently (no return code) but will not modify old.PSSampler making the game crash when accessing uninitialized memory.
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.
