The response time of AutoCAD is sluggish, showing one or more of the following symptoms:
- Commands run slowly or hang after executed.
- Object selection lag.
- Mouse movements are slow, hang, skip, or hesitate.
- The program intermittently pauses or freezes.
- Drawing files are slow to open.
- Files take a long time to regenerate during drawing navigation.
- Turning on hardware acceleration degrades performance.
- Degraded performance over time.
- Dialogs (like plot dialog) are getting opened very slowly.
Slow performance is often caused by hardware or file issues:
- Disconnected or slow network
- Unresolved network drive
- Slow internet connection, when working from remote.
- Drawing tries to connect to a network file (for example external reference, drawing standard, ...), which cannot be opened (permission, locked, file not found, ...).
A file is corrupted.
A file is very large.
- A file has unresolved external references.
- A file has saved a lot of unneeded named objects, including blocks and registered apps.
- The components are placed with high coordinates (thumb rule: > 100.000).
Try the following solutions in order, testing AutoCAD each time. If one solution does not improve performance, proceed to the next strategy:
- If using a wireless peripheral device, such as a mouse or keyboard, check the battery charge level of the device. Install a new batteries.
- Update the graphics card driver (see How to update to the latest certified video driver).
- If using a dual graphics system, such as Intel integrated graphics along with an AMD or NVIDIA card, set AutoCAD to use the high-performance card (see How to configure Autodesk software to use high performance graphics) or
- Discrete GPU does not function as main video controller where dual graphic systems are present (see Dell Article: Precision 5530: Discrete GPU does not function as main video controller).
- If using a laptop computer with an external monitor:
- Try making the external screen the main monitor:
- Right-click the desktop and choose "Display settings."
- Select the external screen.
- Scroll down to "Multiple displays" and select "Make this my main display."
- Restart the computer.
- Switch to only using the laptop screen.
- If slowdowns occur only when the external monitor is attached, check the connecting cables and docking station. Some graphic cards do not support multi-screen setups.
- Try removing extra monitors if using USB connections.
- If connecting to a remote system, confirm that a monitor is connected to the receiving system. Be sure that the remote graphic settings do not conflict with the local settings.
- In AutoCAD, use the GRAPHICSCONFIG command to:
- Turn off "High Quality Geometry" and/or "Smooth Line Display."
- Turn off hardware acceleration. Some systems may work better with this setting turned off.
- Move the file, and all associated files (xrefs, plot file, block references), to the local drive, or turn off cloud-drive-sync for folders already on the local drive.
- Ensure the system is not overheating.
- Check network stability and performance of the network.
- Disconnect unresolved network drives.
- Select the network drive in Windows Explorer and choose from context menu "Disconnect drive".
- Look for unresolved drawings, which cannot be accessed to.
- Open the options and switch to tab "Files".
- Look in all nodes for network paths and check if these network paths are valid and that the user has enough permission to access them
- Open XREF-dialog and check for unresolved external references to validate the file exists at the saved path and the user has enough permission to use it.
- If possible, connect to network drives using an ethernet cord instead of using a WiFi.
- Copy the drawings files locally, work on them locally and paste them back in Windows Explorer afterwards.
- Repair respectively clean the drawing or its external references (see How to repair corrupt AutoCAD files).
- Break a very large file into separate drawings and xref them into a master file (see How to export objects to a drawing file with WBLOCK command in AutoCAD).
- Reload or detach any external references (Xrefs) that cannot be found, are unreferenced, or have broken links.
- Turn off silhouette edges using the DISPHILH system variable.
- Test different visual styles, particularly 2D Wireframe vs. 3D Wireframe.
- Move drawing content closer to 0,0 or use the UCS command to reset 0,0 next to it.
