Tips to Improve Performance in AutoCAD and AutoCAD Based Products

November 6, 2020 Ryan Wunderlich

If you are experiencing lag and /or performance issues while using AutoCAD or it's vertical based products, try the settings below to increase some of the performance and remove some of the program overhead.

  • VTENABLE = 0
  • SELECTIONPREVIEW = 2 or 0 (I have mine set to 0 normally)
  • INPUTSEARCHOPTIONS - Turn off some or all the options, fine tune what you need it to look for and I always recommend increasing the Suggestion list delay time to 3000-5000 milliseconds.
  • Also go into AutoCAD OPTIONS, and under the Display Tab, turn off Display Paper Shadow (and I generally turn off Display Paper Background).
  • Remaining in Options, go to the Open and Save Tab and uncheck Display Digital Signature Information.
  • DYNMODE=0 (this turns off the Dynamic Input, so use only if necessary)
  • WHIPTHREAD=3 (only on 2019 and older), otherwise ensure it's set to 1

Also go into the Control Panel, Select Power Options.  See if you are running High Performance or Balanced.  I generally recommend to select High Performance.
