Drawing preformance related to limits?

I found an AutoDesk tip on drawing performance, named "Improving performance when picking objects or regenerating drawing.

It related this problem to drawing outside of the drawing limits. I was curious about seeing if this may help me when my A2K4 is slow while picking objects.
What I tried to do is set my system variable of Limmax to some thing larger than what most of my drawings would need. I opened my acad.lsp file and entered below the rest of my system variables, that work, the following,
(setvar "limmax" "1088',704'"), I then restarted AutoCAD, however when I open existing drawings, hoping that it will update them, they show something like, 1'-5",0'-11". Is not the acad.lsp supposed to over ride the files variable setting? Am I doing something wrong? Does someone have a LISP or routine that will cause all new or existing drawings to update to a predefined limmax variable?

I do not think ACAD.LSP gets loaded each and every time you open a drawing... you might check your

ACADLSPASDOC
System Variable
Type: Integer
Saved in: Registry
Initial value: 0

Controls whether AutoCAD loads the acad.lsp file into every drawing or just the first drawing opened in an AutoCAD session.


0 Loads acad.lsp into just the first drawing opened in an AutoCAD session

1 Loads acad.lsp into every drawing opened
