Laggy zoom in Illustrator

Hi,

After switching to a new computer, I'm having an issue with laggy zooming in Illustrator; moving objects or the canvas also lags quite heavily. The problem occurs when Overprint Preview is enabled. The complexity of the files doesn’t matter—the issue occurs even when the file is empty and has no objects at all. On my previous computer, using the same version of AI, everything worked fine. I’ve read tons of threads related to this issue and tried all the suggested methods (reinstalling, deleting preferences, GPU preview, etc.), unfortunately nothing helps.

 

Every version of AI lags; currently I’m on v29.6. My computer:

Ryzen 9 9950X
RTX 5060
32 GB RAM
Win 11

 

I’ve made an interesting observation. I currently have two monitors connected: an old Eizo with a resolution of 1920×1200 and a BenQ with a resolution of 2560×1440. When I move the Illustrator window to the Eizo, everything works perfectly. On the BenQ, it lags terribly. However, when the Illustrator window is not maximized, if I pull the window edge just 1 pixel away from the edge and bottom of the screen—it starts working perfectly…

Few computers in company with similar specifications has the same issue.

 

How can this be fixed? It’s very frustrating.

    Are you using a mouse wheel for zooming?

    There are several threads about issues with the mouse wheel. THis for instance. I have no idea whether it has already been solved: https://community.adobe.com/t5/illustrator-discussions/mousewheel-usage-create-lag/m-p/15571942

    Hello @robertw68032793,

    I'm sorry to hear about your experience. Could you confirm if you have tried a clean reinstallation of the GPU(s) drivers (Intel / NVIDIA / AMD) and setting the Graphics Preference to High-Performance for Illustrator (https://adobe.ly/4iqWgEp) and checking if it helps?


    If the problem persists, please share the following information so I can check this with the team:

    1. AiSniffer file:

    - Close all Adobe applications.

    - Navigate to the Illustrator Preferences folder and copy the AiSniffer file to the desktop from this location: 

    %USERPROFILE%\AppData\Roaming\Adobe\Adobe Illustrator 30 Settings\en_US\x64\

     

    2. For the System Report, kindly follow these steps:

    - Please press Windows Key + the letter "R" on your keyboard to bring up the Run command window

    - Type "msinfo32" in the Open field and left-click OK

    - While viewing the Microsoft System Information summary, go to File, then choose Save (Please do not use Export)

    - Save your MSINFO32 report as "msinfo32.nfo" on your desktop to easily locate it after. It can take up to a minute to generate a report.

     

    Kindly upload the files to Google Drive/Dropbox/etc and share a public link here or via DM so that we can investigate this further.

     

    Looking forward to hearing from you.

    Anubhav

    The computer is new, a clean installation of the entire system and all drivers.

    Setting Illustrator to high performance didn’t change anything.
