I'm using pDirect3D->GetAdapterDisplayMode(D3DADAPTER_DEFAULT, &d3ddm); to get the screen size and set the buffers in full screen. However, my screen has a higher resolution than what I want to run the game in. Is there an equivalent SetAdapterDisplayMode? Code complete isn't pulling up anything. Thanks. -Nick

You set it via the present parameters when creating the D3D device.

The width/height/color-depth information can be specified in the D3DPRESENT_PARAMETERS structure that is used in two functions, CreateDevice() and Reset(). The structure contains three members, BackBufferWidth, BackBufferHeight, and BackBufferFormat, that are relevant to your inquiry. Most examples probably just use the values obtained from GetAdapterDisplayMode(), but this is by no means mandatory.
