Illustrator/Windows performance problem

[Kuttyjoe]

I've had this problem since about March of 2020. That's when I bought my current PC.  It's simple.  As long as Illustrator is open, Windows Explorer exhibits performance issues.  The cursor flickers.  If I use the arrow keys to scroll up/down through folders in Windows Explorer, it jumps around and the cursor is flickering. If I try to drag and drop an item, it may lose the item right in the middle of dragging it.  If I grab 2 items and drag them, it may lose one of them along the way.  It is really aggravating and I've never found any reason for it.  But the second I close Illustrator Windows Explorer becomes perfectly normal. Immediately.  Does anybody have any idea what this could be?  I wondered if it might be because this PC has an AMD processor which I haven't used in many years.  I've uninstalled and reinstalled the PC.  The PC shipped with Windows 10.  I upgraded to Windows 11 once but the problem did not go away.  I went back to Windows 10.  I plenty of other software on this PC, Photoshop and other Adobe CC programs, Coreldraw, etc and no other program causes this problem.  Any ideas???  Thanks.

Hello @Kuttyjoe,

We understand that encountering technical issues can be frustrating. Would you mind performing a clean reinstallation of the GPU drivers (Intel / NVIDIA / AMD) and setting the Graphics Preference to High-Performance for Illustrator (https://adobe.ly/43cWKXn) and running Illustrator under Safe Mode (Windows / macOS) to check if it helps?

If the problem persists, kindly share more details, kindly share more details, like the exact version of the OS/Illustrator, system config (CPU/GPU/Memory), and a screen recording of the problem (https://adobe.ly/4catxAh), so we can investigate this further.

Looking forward to hearing from you.

Thanks,

Anubhav

OK thanks for responding.  Right now I'm doing a clean install of my preferences.  I notice that with Illustrator default preference the problem is not happening at the moment.  I've never used the default preference so maybe this is the problem.  If this doesn't resolve it I'll try something else.  But I don't see an option to change Graphics Perferemce to High Performance for Illustrator. Where is that?

I found the high performance setting.  Thanks.
