I understand that you're facing issues with the "View Using GPU" and "Animated Zoom" features in Adobe Illustrator, and you've tried various troubleshooting steps to resolve them. I'd like to assist you in finding a solution to this problem.
Firstly, I recommend that you use the latest version of Adobe Illustrator (v27.9).
Here are some additional steps and information that would be helpful for troubleshooting:
Does this issue occur with specific files, or is it a general problem across all documents? Try creating a new document to see if GPU acceleration works in a fresh environment.
Share a screenshot of your color settings from the Edit menu.
As Doug asked, please provide a screenshot of your entire Illustrator workspace. This will help us understand the context in which you're experiencing the problem.
If there are any error messages or specific actions that trigger the issue, please describe them in detail.
If possible, share sample files where the "View Using GPU" and "Animated Zoom" features are not working as expected. This can help us replicate the problem for further investigation.
Once you've provided this additional information, we can better pinpoint the cause of the issue and offer more tailored troubleshooting steps. Your cooperation is greatly appreciated, and we'll do our best to assist you further.
