Backbuffer resolution

Hi,

When one adjusts a game's screen resolution (you know typically in the game's "Options->Graphics"), is it actually the BackBufferWidth and BackBufferHeight of the D3DPRESENT_PARAMETERS (D3D) for a device, that is being set?

You will have to recreate the whole swap chain to change the resolution of a game, which can be done by recreating the device with the appropriate D3DPresent parameters. But generally it is nicer to just destroy your swap chain and recreated that as that wouldn't force you to reload assets that are created in the managed pool.

Thanks, but I actually want to know if the game's screen resolution is directly correlated to the backbuffer width and height of the present params?

Yes, usually.
