Is your SQL statement (copied from the View Designer and run from the command window or a prg) running asynchronously? (Tools | Options | Remote data tab, Asynchronous execution check box) This means that the first data begins to show while the remaining data is still coming down the wire.

Another idea: When I used the view designer against a large (many tables) database, it seemed to be querying the database for something every time I opened it. Whatever it is, this does not happen in SQL pass-through.
