Improve AutoCAD performance with these 14 system variables

To improve AutoCAD performance you can tweak some settings related to the operating system and your hardware.

These software and hardware changes will speed up AutoCAD as explained in this article.

But apart from making these changes, there are also some default settings which can be changed using system variables to visibly enhance the performance of AutoCAD.

In this article, I have listed fourteen such system variables.

ZOOMFACTOR

This variable will change the speed with which scroll wheel of the mouse will zoom the drawing area.

If you are a beginner then try to change the ZOOMFACTOR variable to 30 range which would be easy for you.

The Default value is set on 60 which will be suitable for most of the cases but if you want more speed you can change this variable to 100.

WHIPTHREAD

This variable specifies how AutoCAD will use additional processors on the machine.

If there is only a single processor then this variable will not have any effect.

By the way you can know more about selecting the best hardware and best laptop for AutoCAD here.

The default value of WHIPTHREAD system variable is 1 but you can change it to other values as well.

0 – No multithreading used

1 – Regeneration only is carried out by multiple processors

2 – Redraw only is performed by multiple processors

3 – Regeneration and redraw carried out

AutoCAD can use that extra processor to improve the speed of operations such as zoom which redraws or regenerates the drawing.

There will be a slight acceleration when you are working with large drawings if you set this variable to 3.

But you should not expect a drastic improvement in the performance just by changing this system variable.
