AutoCAD offers multiple ways to open the Graphics Performance dialog, where hardware acceleration settings can be adjusted. You can access it by:

Typing OPTIONS, navigating to the System tab, and selecting Graphics Performance.
Using the GRAPHICSCONFIG command and clicking Hardware Configuration.
Typing 3DCONFIG and selecting Hardware Configuration.
Clicking the GRAPHICSCONFIG performance button in the lower-right corner of the AutoCAD window.

For users of AutoCAD LT 2011 or earlier versions, keep in mind that these versions don’t support hardware acceleration, so the 3DCONFIG command won’t be available. If the Graphics Performance dialog appears off-screen, press Alt+Spacebar, then M, and use the arrow keys to bring it back into view.

Disabling Hardware Acceleration

Once the Graphics Performance dialog is open, locate the Hardware Acceleration option. Slide it to Off and click OK.

For those working in virtualized environments, such as on a Mac using Parallels, disabling hardware acceleration can lead to more consistent performance. In these setups, hardware acceleration may not function reliably, so switching to software-based rendering is a better choice.

Verifying the Changes

After turning off hardware acceleration, test AutoCAD to ensure the changes resolved the issue. Perform your usual tasks, such as drafting, 3D modeling, and navigating complex drawings.

If crashes or graphical glitches no longer occur, it’s a clear sign that hardware acceleration was the source of the problem. Keep in mind that while some actions like panning, zooming, or 3D operations might feel less smooth, the stability gained often outweighs the slight performance trade-off, allowing for a more reliable workflow.

Updating Graphics Drivers for Better Performance

In addition to disabling hardware acceleration, keeping your graphics drivers and operating system up to date is essential to avoid persistent AutoCAD crashes. Outdated drivers are a common cause of hardware acceleration issues, leading to frequent crashes, display glitches, and sluggish performance. By ensuring your drivers are up to date, you improve compatibility and stability with AutoCAD.

For macOS users, navigate to System Preferences > Software Update to check for updates. Apple frequently includes graphics driver updates in system updates, especially for newer hardware.

After updating your operating system, double-check that your graphics drivers are still current. Occasionally, OS updates can overwrite drivers, requiring you to reinstall the latest certified versions from your graphics card manufacturer.

Finally, monitor AutoCAD’s performance after each update. If you experience new stability issues, visit Autodesk’s support forums for guidance on compatible driver versions for your setup. Regularly updating both your drivers and operating system ensures AutoCAD runs smoothly, complementing earlier changes to hardware acceleration settings.

Clearing Graphics Cache and Resetting AutoCAD

Sometimes, persistent hardware acceleration issues in AutoCAD can be traced back to corrupted cache files or misconfigured settings. AutoCAD uses graphics cache files to boost display performance, but these files can get corrupted over time, especially when handling complex 3D solids or surfaces. Clearing the graphics cache and resetting AutoCAD to its default settings can often fix these recurring crashes.

Clearing AutoCAD’s Graphics Cache

The graphics cache in AutoCAD stores data from recently processed graphics, allowing the software to access it quickly without reloading the original files. However, if these cache files become corrupted or your system is bogged down by large, complex graphics, crashes and slowdowns can occur. If AutoCAD disables hardware acceleration due to graphics-related problems, clearing the cache is a common solution.

To clear the graphics cache using AutoCAD commands:

Open any drawing in AutoCAD.
Type CACHEMAXFILES into the command line and press Enter.
Set the value to 0, which disables caching, and press Enter again.
Close AutoCAD completely and reopen it. This will automatically clear the contents of the GraphicsCache folder.
After restarting, reset CACHEMAXFILES to 256 to re-enable caching.

If you prefer manual deletion, you can directly remove the cache files from your system. Here’s how to locate the GraphicsCache folder:

For standard AutoCAD installations:

C:\Users\[Your Username]\AppData\Local\Autodesk\[AutoCAD 20xx]\[Rxx.x]\[enu]\GraphicsCache

For AutoCAD-based products like Civil 3D:

C:\Users\[Your Username]\AppData\Local\Autodesk\[Product Name]\[enu]\GraphicsCache

Simply delete all files in this folder. If clearing the cache doesn’t resolve the issue, the next step is to reset AutoCAD’s settings.

Resetting AutoCAD to Default Settings

If clearing the cache doesn’t fix the problem, resetting AutoCAD to its default settings might help. This is especially useful if hardware acceleration remains disabled after updating graphics drivers or if other persistent issues continue. AutoCAD provides a Reset Settings to Default utility that resolves configuration conflicts without affecting your drawing files or plugins.

Here’s how to access the reset utility:

Windows 11: Go to Start > All Apps > AutoCAD 20xx > Reset Settings to Default.
Windows 10: Navigate to Start > AutoCAD 20xx > Reset Settings to Default.

Before resetting, back up any custom settings you want to keep, such as tool palettes, workspace configurations, or plotting setups. The reset will revert all interface customizations to their original state.

Restarting AutoCAD to Apply Changes

After clearing the graphics cache or resetting AutoCAD’s settings, a full restart of the software is necessary. Simply closing and reopening drawings won’t suffice – you’ll need to exit AutoCAD completely and then relaunch it.

Once AutoCAD restarts, test the changes by re-enabling hardware acceleration through the Graphics Performance dialog. Pay attention to how the software behaves during the first few sessions. This will help you confirm whether the issue has been resolved.
