Is Illustrator running slowly, is the mouse lagging, or is zooming jerky? Most often, these are preferences corrupt, a poorly managed GPU or a file that's too large—rarely your PC.
Here are the settings to test in July 2026, starting with the most effective as simple as possible, and without third-party software.
✅ At a Glance: 5 Settings to Try
- Reset Preferences Illustrator (free, 30 seconds).
- Check your RAM and optimize your file (linked images, unnecessary layers).
- Test the GPU in both directions: often, simply turning it off is enough to make it run more smoothly.
- Embed the images embedded rather than leaving them as links.
- Update Illustrator and clear the cache.
Do them in this order : We'll start with the quickest and most effective method.
Tip #1: Reset your preferences
First and foremost complicated adjustment, start with this: it’s the first step experts recommend—it’s free and quick. It doesn’t solve everything, but it eliminates the most common cause of sudden slowdowns: a corrupted preferences file.
The principle : Close Illustrator, then restart it by holding down a key combination just before it opens.
- On Windows : Hold down Ctrl + Alt + Shift while launching the program.
- On Mac : Hold down Cmd + Option + Shift while launching the app.
A window will appear asking you to confirm the removal of settings : Click OK. Restart Illustrator, which will then open with new preferences, reset to their default values.
⚠️ Good to know : This action will also reset your personal settings (workspaces, custom keyboard shortcuts, interface colors). Make a note of any important settings before proceeding.
Tip #2: Test GPU acceleration
Counterintuitive, but for many users, disabling the GPU is what makes Illustrator run smoothly again.
In theory, GPU acceleration makes zooming and panning more fluid. In practice, on many systems (older graphics cards, integrated chips, poorly managed drivers), it causes the opposite effect: mouse lag, stuttering, a white flash, or even the option turning itself off.
The right approach, therefore, is to test in both directions:
- If Illustrator is running slowly, glitches, or stutters: Go to Edit > Preferences > Performance and uncheck «Enable Graphics Processor.» You can also switch the preview to CPU mode via View > CPU Preview.
- If it's just a little soft and if you have a recent graphics card: leave the GPU enabled, but update your graphics drivers (NVIDIA, AMD, or Intel). Outdated drivers are a common cause of crashes and slow performance.
👌 The Right Instinct : Try both configurations on the same file and keep the one that works best.
On macOS, you cannot do not update Graphics drivers are updated independently: they are included in system updates.
So just check to make sure your Mac is using the latest version available in macOS, then test the navigation speed in your document again to see if it makes a difference.
Tip #3: Reduce the size of your file
A file packed with linked high-resolution images is enough to bring Illustrator to its knees, even on a good machine. Before blaming your computer, try lightening the load on the project.
Integrate Your linked images. A simply linked image forces Illustrator to reload it constantly. Open the Window > Links panel, select your images, and then choose "Embed Images" from the panel menu. The difference with large files is often dramatic.
Hide unnecessary layers. In the panel Layers, click the eye icon next to each layer you're not using. The fewer elements Illustrator has to display, the faster it responds.
Reduce thumbnails From the Layers panel. Go to the Layers panel menu > Panel Options, then reduce the thumbnail size (or turn them off). They use up display resources for no reason.
Use a low-resolution proxy for linked EPS files. If you're working with large EPS images, go to Edit > Preferences > File and Clipboard Management, then check «Use a low-resolution proxy for linked EPS files.».
📌 Hardware : 8 GB of RAM is currently the minimum requirement for Illustrator. If you can, upgrading to 16 GB makes a huge difference. Otherwise, the tips above will go a long way toward compensating for the lack of RAM.
Additional Settings (if the problem persists)
These settings have less impact, but they're worth it if the first three weren't enough.
Disable fonts superfluous. Having too many fonts installed (or duplicates between Adobe and Office fonts) slows down startup and display. Disable the ones you don't use.
Update and empty the hidden. Always work with the latest stable version of Illustrator and your operating system. Updates are designed to fix many performance issues and display bugs. Take this opportunity to clear Illustrator's cache.
Speed up Windows startup. Too applications Programs that run at startup use up your RAM before you even open Illustrator. The safe way to do this: Press Ctrl + Shift + Esc to open Task Manager, go to the Startup tab, right-click on any unnecessary applications, and select Disable. (There’s no need to manually move system files.)
Advanced settings, The working disk. In Edit > Preferences > Plug-ins and Working Disks, set the primary working disk to your fastest disk (ideally an SSD that is different from your system disk). This is especially useful if you're working with very large files.
In last resort : Roll back to a previous version. Some versions of Illustrator have been reported by users as unstable. If the slowdown began immediately after an update, reinstalling the previous version through Creative Cloud may resolve the issue.
FAQs
Why is Adobe Illustrator so slow?
In the vast majority of cases, the slowness is due to three things :
- Corrupted preferences; ;
- A poorly managed GPU; ;
- The file is too large.
You rarely need to replace hardware to fix the problem.
How can I improve Illustrator's performance without buying a new computer?
Reset the preferences, Test the GPU in both directions and reduce the file size. These three settings are enough to speed up Illustrator on most systems.
How much memory do I need to use Illustrator comfortably?
8 GB of RAM is currently the minimum requirement. If you can, upgrading to 16 GB of memory really makes a difference in your day-to-day experience.
Is the solution the same on Windows and macOS?
Yes, with one exception : On Windows, be sure to update your graphics drivers, whereas on macOS they are included in system updates.
In a nutshell
The slowness of Adobe Illustrator can be attributed to: preferences corrupt, a poorly managed GPU, or a file that's too large.
start with reset preferences, test the GPU in both directions, reduce the file size, and take this opportunity to clear Illustrator's cache—you should then be able to run the software smoothly without changing your hardware.
