tips and links.
Tips and Tricks
Need to compile your application using the
Direct3D 8.0 interfaces, but using the DirectX 8.1 SDK? It's easy - just
specify a value of 120 in your call to Direct3DCreate8(), rather than the
value of D3D_SDK_VERSION specified in the docs. This will cause your
application to generate the Direct3D 8.0 interfaces at runtime, rather than
the new 8.1 interfaces. This is useful if your application must support
Windows 95, which is not supported under DirectX 8.1, or if you want to
support users with DirectX 8.0 runtimes rather than requiring an upgrade to
8.1.
