How to make AutoCAD Open Faster and Run Faster


A common goal for every AutoCAD user is to get the best performance out of your AutoCAD software. And some of the old tricks still hold true today–they are just done a little bit differently in the newer versions.

So, I thought I would take some time and show everyone how some of some old tricks that help AutoCAD run faster.

Reducing the Amount of Content to Load When Starting AutoCAD

Right-click on the AutoCAD desktop Icon and click Properties.

Click lick in the short and add the switch “/nologo” at the end of the line in the Target field.

Example: “C:\Program Files\Autodesk\AutoCAD 2017\acad.exe” /product ACAD /language “en-US” /nologo

Click Apply at the bottom. (You will need to have administrator permission to do this)

Click OK to exit the properties dialog box.

Setting the Priority in the Task Manager

Launch AutoCAD so the executable displays in the Task Manager.

Right-click on the Window’s start icon and open the Task Manager.

Click on the Details Tab.

Right-click on the ACAD.EXE file.

Click the Set Priority.

Select Realtime option.

Close the Task Manager by clicking the X in the upper-right corner of the dialog.

Setting the Hardware Acceleration

Open AutoCAD and check the Hardware Acceleration icon to see if it is ON.

(If OFF, follow the steps below to turn it ON)

graphics performance

Right-click on the Hardware Acceleration icon and pick the [Graphics Performance] shortcut menu.

Other ways you can test to see if you are getting the best performance is to test some of the settings by turning them on and off.

For example: Open the Hardware Acceleration the same way you did in the last Item. You can also view the Tuner Log.

Additional Notes from the AutoCAD Help file:

Graphics performance tuning examines your graphics card and 3D display driver and determines whether to use software or hardware acceleration.

Features that might not work properly on your system are turned off. Some features might work with your hardware, but are not recommended because the graphics card or 3D graphics display driver that you are using did not pass the Autodesk certification process or was not tested. Features can be enabled at your own risk.

The tuner log reports which graphics card and 3D display driver were identified on your system and whether hardware effects are enabled. The Effects section displays the current state of the supported hardware effects of the current display driver.

The log file displays information about the current application driver, as well as available application drivers and supported effects. Use this information to determine whether it’s better to use an application driver for your graphics card or the software driver.

To display mapped object shadows in viewports and to use per-pixel lighting, hardware acceleration is required.

When Uncompressed Textures is turned on, the amount of video memory required to open a drawing that contains materials that utilize images is increased.

By using this effect, it may decrease the time to load the images the first time that they are accessed, but the downside is it can increase the amount of video memory necessary to display the drawing. Also, there is a reduction in the quality of the images when they are displayed.

Finally, always make sure that your Hardware (including Graphics Card) is tested and Certified by Autodesk.

And when it comes to RAM, more is always better!

Remember, the recommend amount is just to run the software, not your business!
