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)
- LAYOUTREGENCTL = 0
- -INPUTSEARCHOPTIONS - Either turn off all the options, or increase the time delay into 5-10 seconds.
Type in INPUTSEARCHOPTIONS and turn off Search in System Variables, and set the delay to 3000 milliseconds...this is usually the killer on slower machines
- 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.
