This error occurs only if the resolutions is greater than 640x480 px. This error doesn't occur if the game is started at 640x480px.
LOK Soul Reaver program relays on winplay.dll, which provides some helper functions. I guess its related to some old DX functions, that are not implemented (in correct manner).
