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.
