My system started acting up and I can't figure out why. Never had this problem before.

 

When I am in ISO view and chose anything other than wireframe, like "Realistic"  panning and zooming are very slow. Even a smaller drawing does not act normal. I use a 3rd party software for modeling ductwork and piping, the drawings work fine on our other machine, so it's not the modeling software. It's also not the drawing file, I have tried other drawings that I had no past issues with but it still bogs down.

 

I have tried the following:

Updated video driver.

Tried different settings under "Options" "Display" and "3D Performance"

Ran AutoCad repair.

Checked and turned off all snap settings and grid.

 

I am lost, any help would be appreciated.

Did you purge and audit the drawing?

Are xrefs attached?

Yes, I have purged audited and detached XREFS with very little effect.
I even moved the files to my local drive thinking it was a network issue, but no difference.

Hello, have you done SCALELISTDELALL on your files ?
You have to do the command APPLOAD with the file : ScaleListDe.lsp.

You say it happens ONLY with this one drawing.  Maybe the file is corrupted.

When you purged did you use the command line version and purge Regapps first?

You don't use Grid and Snap by any chance when you do an isometric?
