 You can specify the written trace filename by setting the `TRACE_FILE`
 environment variable before running.
 
+For D3D10 and higher you really must use `apitrace trace -a DXGI ...`. This is
+because D3D10-11 API span many DLLs which depend on each other, and once a DLL
+with a given name is loaded Windows will reuse it for LoadLibrary calls of the
+same name, causing internal calls to be traced erroneously. `apitrace trace`
+solves this issue by injecting a DLL `dxgitrace.dll` and patching all modules
+to hook only the APIs of interest.
