    Default Re: Better dual-core support

    Does the current WHIPTHREAD AutoCAD system variable improve your regens?
    From AutoCAD 2006 Help File

    Type: Integer
    Saved in: Registry
    Initial value: 1

    Controls whether to use an additional processor to improve the speed of operations such as ZOOM that redraw or regenerate the drawing. WHIPTHREAD has no effect on single processor machines.

    0 No multithreaded processing; restricts regeneration and redraw processing to a single processor. This setting restores the behavior of AutoCAD 2000 and previous releases.

    1 Regeneration multithreaded processing only; regeneration processing is distributed across two processors on a multiprocessor machine.

    2 Redraw multithreaded processing only; redraw processing is distributed across two processors on a multiprocessor machine.

    3 Regeneration and redraw multithreaded processing; regeneration and redraw processing is distributed across two processors on a multiprocessor machine.

    When multithreaded processing is used for redraw operations (value 2 or 3), the order of objects specified with the DRAWORDER command is not guaranteed to be preserved for display but is preserved for plotting.
    If you have a technical question, please find the appropriate forum and ask it there.
    You will get a quicker response from your fellow AUGI members than if you sent it to me via a PM or email.
