I am writing a game using the Jedi DirectX libraries. I have noticed that
DirectX slows down greatly when Blitting to a panel in a windowed
application vs. a full-screen application. I think that there is some
underlying Form painting going on that is slowing down DirectX. Here is the
code snippet:

if dest.Blt(@dest_rect, bob.images_DD7[bob.curr_frame], @source_rect,
(DDBLT_WAIT or DDBLT_KEYSRC), Nil) <> DD_OK then
begin
Result := False;
Exit;
end;

The resulting Blt works but the overall game loop is very slow so the
animation lags. Any ideas on how to speed things up? Is there some Delphi
form setting I can change? Thanks!
