Illustrator 27.1.1 - GPU Preview greyed out

Hi @iamfablaz2018,

Thanks for reaching out and reporting the issue. Recently many users have reported this, and we have logged a bug with the product team. They have started the investigation. The majority of users are using NVIDIA cards and are on the windows machine. This is happening for users while working on some specific files. Would it be possible for you to share a few files in which you experienced this behavior? It would be really helpful for us.

Also, would you mind confirming the OS build no, GPU VRAM, GPU driver version, the exact version of Ai, CPU details & does the CPU has integrated Intel/ AMD GPU?

I will be looking forward to your response.

Thanks,

Don't bother resetting preferences or anything that Adobe suggests like re-installing or anything like that. It is very well documented at this time that illustrator 27 has a huge amount of GPU acceleration problems. I guarantee you if you revert back to a previous version of Illustrator like 26.2.1 you will not have any GPU problems whatsoever. I am waiting for Adobe to say that they are working on the fix. Would be good to know if they acknowledge it.

If you use the keyboard shortcut Control-E does the GPU Preview come back? I was unable to duplicate the problem on a Mac (same version of Illustrator on Monterey 12.6.2). Has this only been happening since you upgraded to 27.1.1? If so then try resetting your Illustrator preferences. This will restore the program to its default which could fix the issue.

To reset preferences on a PC:

You can try the quick way of resetting on a PC which is to hold down Ctrl + Alt + Shift when launching Illustrator and respond affirmatively when asked if you want to reset. There have been some recent reports that the window asking if you want to reset is not popping up but that the prefs are being reset anyway. If this works great but if it doesn’t you may have to manually delete them.

To do so: On Windows 7 and above the preference files are hidden. To find them go to the Control Panel and open Folder Options and then click the View tab. Then select “Show hidden files and folders” or “Show hidden files, folders or drive options” in Advanced Settings. Then delete (or rename) the folder at the end of this path: C:\Users\[User Name]\AppData\Roaming\Adobe\Adobe Illustrator [version number]\ Settings\<Language>. Make sure that Illustrator is closed when you do this. When you relaunch the program it will create new preference files and the program will be at its default settings.

The advantage of manually deleting preference files is that after you’ve reset up the program (make sure that no document window is open) to your liking, you can create copies of your personalized “mint” preference files (make sure that you quit the program before copying them—that finalizes your customization) and use them in the future to replace any corrupt versions you may need to delete.
