Increase AutoCAD Performance

Close unnecessary applications. Identify programs that are running and close those not needed for your current application. The operating system allocates RAM to all open applications – not just the active application. Use the Windows Task Manager (CTRL+ALT+DEL) to identify running applications and processes and click End Task to shut down any unnecessary applications. (Check with IT staff before deleting)

FDOs. Consider linking to images as FDOs (Feature Data Objects) rather than using the Map > Image > Insert command.

Reduce the amount of information you are working with. Simplify the drawing. Avoid hatching large areas. Unload unnecessary images and/or XREFs. Avoid excessive use of TrueType based text. Close all drawings not necessary for the current task.

Set LAYOUTREGENCTL = 0. This system variable can improve performance by not saving the layout tabs to memory. When LAYOUTREGENCTL is set to 1 or 2, the amount of additional memory used is the size of the Model tab's display list multiplied by the number of viewports in each layout for which the display list is saved.

Empty TEMP folder. (C:\Documents\Resolve) Empty your temp folder on a regular basis.

Set FIELDEVAL = 4. Fields are only evaluated on plotting thus saving from constant regens.

Set INDEXCTL = 2. This will index the drawing making any further work in it much quicker.

Layout REGEN options. Set the Layout Regen options to Cache model tab and last layout. The drawing will not regenerate each time layouts are switched.

Set LAYEREVAL = 0
