The marquee zoom tool is not working correctly in CC 2019. Previously you could turn "Zoom to selection" on or off. In CC 2019 this option is still available under preferences, but regardless if you turn it on or off, the marqee zoom feature only works if you're in overprint preview or wireframe. When in GPU Preview, only "Zoom to selection" works, even if you have it turned off.

MacOS Sierra 10.12.6
Mac Pro (Mid 2010)
Processor: 2.8 GHz Quad-Core Intel Xeon
Memory: 16 GB 1066 MHz DDR3
Graphics: ATI Radeon HD 5770 1024 MB

I have animated zoom enabled on my system, and I've made sure to View using GPU, but animated zoom doesn't work.

Illustrator 23.0.6 64 bit on Windows 10 desktop.

Ryzen 7 2700X
16 GB DDR4
GTX 1080

Works for me. Have you got GPU active?

@ADMIN Ashutosh Chaturvedi: This has NOT been fixed in Illustrator 23.0.2 (the latest release as of Mar 4, 2019).

I'm getting two different behaviors of zoom. When I'm in GPU i get scrubby zoom. When I'm in outline I get zoom to selection. I'm on the latest illustrator CC with auto updates and windows 10 (non insider)

I would really, really like the option to turn off animated zoom in outline mode. I really prefer the marquee zoom and would be a much happier user if I could toggle it in the preferences. Thanks!

@Qwertworks uncheck Preferences/Performance/Animated Zoom

Is there an option to switch between these two zoom methods? Because I actually like the marquee zoom tool. I find it very efficient in zooming in and out very fast.

1. Reduce the track thickness display in outline / GPU view
2. Assign a keyboard command to the new bleed view. W button
3. Enable Smart Guides in bleed view
4. Increase zoom levels above 64,000%. The sò has just been increased, but for the precision of the design sometimes 64,000% is not enough

The problem is that effects are ON i outline mode, you just can't see them. I have no idea why. If you have an objects with let's say a heavy gaussian blur to it and you ty to scale it in outline mode, the effect is still loading even if you can't see it. It doesn't make any sense.

When I'm working on a document and if I change to Outline mode the program is unable to zoom out and becomes unresponsive, to the point that I need to close the file and open it again. After I do that the file works again but the dynamic zoom feature no longer works and reverts to how the zoom feature used to work on previous versions.

Outline mode is currently unbearably slow for some configurations. There are many related threads and it seems Adobe is admitting the issue and working on an indirect fix (adding animated zoom to preview-mode, which requires adding GPU-acceleration as well).

Been going on for more than a year! Happens on latest mbPro, iMac, iMac Pro, etc…

Only workaround afaik: finder > illustrator.app > right click > open in low-res mode. Looks like ****, but works fine even on a 5K external display.

Looks like you guys need a visit from Don Norman and Jakob Nielson! Usability is a tad flawed wouldnt you say —after 20 iterations of illustrator... Time to get it right! Why does Astute Graphics have to create plugins to solve these standard usability issues.

The outline preview in general is just terribly slow. Wouldnt their be a way to improve redraws as you scroll around and zoom in and out of screen? Im using a $3k usd imac. Illustrator was faster 15 years ago.

WOOHOO!

Ya'll should also post:
1. Your version of Adobe Illustrator
2. Operating System

Just adding even more info:

Illustrator doesn't need "animated zoom in outline-view", it needs GPU acceleration in all view modes.

The bigger the viewport the slower the refresh rate seems to be. Only GPU accelerated preview offers acceptable speed. Turning off GPU acceleration entirely makes everything much slower even. External displays (again, higher resolution = more pixels) cause the refresh rate to drop significantly.

Outline-view (as it doesn't support GPU acceleration) is a lag-monster like it never was before.

Quoting Joaquin from below, again:

"Ilustrator needs to be SUPER responsive and snappy in Outline Mode like it was before the MacBook Pro Touch was released".

Please let us know how can we assist/help and make you understand and solve the issue!

Only small viewports guarantee fluid performance in all view modes (GPU-preview, regular, outline-view). Happening for 12 months. Seems to be an issue for a lot of users.

1. Latest Version, but applies to all CC…

2. Related to existing and new documents. Reset prefs, reset OBOE, new user account (MacOS), fresh installation. New hardware purchased.

3. Blazingly fast performance

4. Still the worst performance ever experienced

We've been experiencing the same issue since Ai2015 on our 5k iMacs. Performance suffers so much that CPU Preview mode is essentially unusable, which is a shame because the artifacts and errors introduced by GPU mode have been a headache to deal with.
