That's normal using CPU preview. But not being able to activate GPU preview is not normal. Does it work if you restart Illustrator and open a blank document?
Yes, that was strange. However when i restart and open this same document, it shows that i am actually using GPU preview (not like in video). But it is lagging also.
We are sorry for the trouble. Many windows users have reported this issue recently. Would you mind confirming the exact version of OS (build no.) & Ai and sharing your system specs? Also, would it be possible for you to File> Package and share some sample files, including the linked images/files in which you are facing this issue? It would be really helpful for us to investigate the issue further.
I will be looking forward to your response.
I have tried 3 different versions of AI - 2021, 2022 and 2023.
Windows 11 22H2, build no. 22621.963
laptop Legion 5 pro: 32 GB RAM, AMD Ryzen 7 5800H with Radeon Graphics 3.20 GHz, GPU: Nvidia RTX 3070 mobile.
What are you using to give you the size of the image files? If they are JPGs, open one in Photoshop and check the file size there. JPGs are uncompressed when opened in AI so the file size can grow to unmanageable sizes.
Thanks for sharing the details. It would be really helpful if you File > Package and share some sample files, including the linked images/files in which you are facing this issue. We will check on our end and share our observations with you.
Also, would you mind checking if this is happening in a new blank document or if the behavior is only happening in some specific files?
We are here to help. We just need more info.
Hello. I can't share my document, since my trial has expired. But I created a lag test document in which I have 3 (same) pictures in there and it lagging quite a lot. They are big in size but i dont think it is the problem. Basically if i have any document with like 5 photos of 3mb size it is lagging. When i add photos, it lags more and more.
Thanks for sharing the details, @Michal27518026v9dh. I used multiple images, more than 10 with 5 -10 MB size HEIC files, and I am not facing the lagging. Do you recall if the images were embedded or linked in the document?
If the images were embedded, it could make Illustrator lag, and if they were linked but stored on a network drive, it could cause a lag if there are discrepancies in the network. Also, if GPU preview is disabled or not turned on, then there can be lag on CPU preview.
I hope this helps!
Thanks for reply. Images were linked in my own computer. GPU preview is enabled.
