Performance of overprint preview mode and GPU preview mode
Im form a print and packaging industry.
- we frequent work in overprint preview mode but when we switch to overprint preview mode we feel death slowness in the illustrator performance and also checking for the seperation preview is also very slow.
it take minimum of 3 to 8 second to zoom in the artwork
- some time in GPU preview mode we see a red strip above the rulers
Please have a look at the snap shot for our system specifications
and I use Illustrator V23.0.1

Totally agree. This performance bug needs to be fixed asap. Overprint preview mode is way too slow and seems to keep getting slower with every update. We need performance with animated zoom while in overprint preview mode as well.
Overprint preview mode needs GPU performance, the animated zoom is painfully slow especially when working on hires print layout documents.
The bug with the red strip when switching back and forth needs to be fixed too.
Bought about 30 brand new fully loaded i9 MacBook Pros (2019) with Asus 32" 4K ProArt external monitors for my studio. Day one after deployment, users started complaining about a lag that many said they couldn't tolerate. That lag didn't' exist with the older fully loaded i7 MacBook Pro laptops with Apple Thunderbolt displays. So, needless to say, after spending over $150,000 on studio equipment, I had a pretty big issue on my hands. I immediately started reaching out to Adobe and to Asus. Asus swore their computer wasn't the issue. We went through various adapters, cables, etc. And Adobe swore it wasn't their application. But, it was a combination of both!
If you look on Adobe's website for minimum requirements for Adobe Illustrator, it has ridiculously low specifications (Multicore Intel processor, 8 GB of RAM, 1024 x 768 display, 2 GB of available hard-disk space, Mac OS 10.13, 10.14, 10.15). Our equipment exceeded that by far! What they don't tell you is that if you go over the 1024x768 and jump to 4k that you need to be running 60hz on your monitor! I advised them to update their minimum requirements to include this information but I see it still hasn't been included. I bet all of these forums with users having issues wouldn't exist if that info was updated.
Ok, so that was the first part, acknowledging the software needed 60hz monitor to run smoothly. Well, out of the box, my Asus ProArts only ran 30hz. Reading the manual, Asus claimed the monitor could achieve 60hz by HDMI 1 port . You would think the cables that came with the monitor would work, nope! Had to buy several adapters and cables to finally find what allowed the Mac to see the proper refresh rate and resolution. Asus support was no help. I replied back to them with what did work with detailed instructions on what ports and how to get the the selections from the displays preferences. I tried everything but only the Display Port was able to achieve the 60hz at 4k.
So, after getting the appropriate fast 4k 60hz cable (don't do adapters, just do a cable convert direct connect from computer to monitor) and seeing that the monitor was at 60hz, Illustrator worked with NO lag!
If you are using an Asus ProArt monitor, here's the information I sent them on getting it to work. Hopefully this information might help another person. The time/money wasted between Adobe and Asus was horrible.
ASUS ProArt 60hz Steps:
1. Buy USB-C to Display Port conversion cable (https://www.amazon.com/gp/product/B075V27G2R)
2. Plugging in that cable from any of the USB-C/TB3 ports on the MacBook Pro to the Display Port of monitor
3. Change the stream of the Display port to 1.2 from the monitor menu (System Setup > DisplayPort Stream > DisplayPort 1.2)
4. Change the display resolution via advanced method. Enter advanced mode by going to File > System Preferences > Displays, hold down the option key and click on “Scaled”. Click the “Show low resolution modes” to reveal “Refresh Rate”. Select a non-low resolution and select “60 Hertz (NTSC)” from the Refresh Rate option.
This should resolve your problem!
Overprint preview working very slow with 4k monitors on v24.2
What I found is really interesting if you want drasticly speed up performance of Illustrator. Illustrator is much more faster when you are using high refresh rate of the screen. I found this accidentally plugin by side car the ipad pro 2gen (120hz) improved smoothnes and resposivness of the applications. Also decrease much more the delay when resizing object. And yes this is truth, today I have made 2nd test and plugged my gaming monitor (refresh reate up to 144hz) to the iMac and the Illustrator is super fast.
Of course there is a difference when you resize one shapes (rectangle) and when youdraw second and catch both to resie there is a little bit delay but overall experience is awesome on high rate refresh monitors.
This is wired because high refresh monitor are not common in graphic design, because of lack of color accuracy and gamut. The best graphic monitors are on 60hz refresh rate. You have to check this out.

Federico Platón you are absolutely right.
My specs are:
Windows 10 Pro 64bit
AMD Ryzen Threadripper 1920 and AMD RX 580 8gb DDR5 video, Samsung 27" 4k monitor.
You must agree our computer are similar enough to rule out raw computer power.
Also my problem was with a A4 blank document so clearly is a compatibility problem with some specific hardware.
I know is not possible for Adobe to test their software on every piece of hardware on the market but their minimum system requirements are a bit generic.
I'll try and do some more tweaking and testing and see if i get to the bottom of this.
(For now i manage to improve the time by 1-2 sec only by changing the monitor refresh rate so will see where this leads)

I am on Windows 10 with a i7 8th generation.
My monitor is a Dell 27"at 5K.
And my graphic card is a Nvidia GTX-1060 with 6Mb Vram.
I have set a document 2 feet side, with a big text and three squares covering more than half of the artboard, items set to overprint and uplicated about 5 times each. Also have tried scaling all up, including the aartboard, 10x with the same result:
Under 2 seconds to preview. Zooming up/down entering Outline view and going back to Preview overprint takes less than 2 seconds.
I think the graphic card is the main or only player here.
If you use Overprint mode on a 4k or 5k display you need a lot of processing on the graphic chip.
Nvidia seems to have shown a better behaviour with Adobe apps.

Same problem here. Illustrator 24.2 (64 bit).
Even with a blank document zoom in/out with overprint preview off is instant.
When i activate overprint preview it takes 3-4 seconds to zoom in out.
Problem appear only working on display resolution above 4k on a last generation pc on a 6 year old mac with 2k monitor everything is perfect.
It appear the illustrator has some serious compatibility issues with some CPU/GPU.
Adobe should provide a strict list of hardware that is compatible with their software because is ridiculous to invest maybe thousand of dollars in one only to find out is not usable and a 6-10 years old computer works better
Can we get a fix on this - literally no designer worth their salt uses 1920x1080 anymore.
Hey guys, I have the same issue with very laggy over print view and very big latency with transforming rectangle, circle or other vector shape. The line of the vector is far behind the cursor... you feel some kind of delay... and not smooth moving over the canvas by hand tool. here I record the video with this problem: https://youtu.be/mtCttOjDMeM

I got help with this issue from an online session from the peeps over at Adobe. i'm using Illustrator 20.0.1, with a 2019 16' MacBook Pro, Mac OS Catalina 10.15.2.
I spend most of my time in overprint too, and apparently Adobe is backlogged with other bugs and working their way to this issue. In the mean time, they suggest either not working in overprint, or if you have to, press CMD+Y to go to line mode when in overprint to avoid the lag.
The issue is due to legacy software changing up to a 64bit systems. So yeah, guess we're stuck until Adobe solves this.
I bought 46 (Yes, Forty-Six) i9 Apple laptops with paired 32" Asus ProArt 4K monitors. I've included the hardware specs below but we are having the same/similar Illustrator (CC2019) issues. General functionality is impacted by slowness/delays on moving objects, manipulating paths, moving the canvas around, etc.
I have also found that it appears to stem around high resolution display settings. Using the 4K monitor but dumbing down the display resolution lower than 1080 gives a lot more fluidity and the issue is almost not apparent however, going above 1080 resolution triggers the issue. The delay also gets gradually worse the higher the resolution you set. Forget using your new 4K monitor at that resolution!
Also, the delay gets worse as your file grows too! The increasing number of points/effects/art boards/layers/etc all start to contribute lengthier delays. This is not experience of one artist, it's all of them! Fresh installs of Mac OS and Adobe Software, wouldn't be an "upgrade" issue here. To help determine these issues, we have: disabled “Print Preview”, tried GPU/CPU processing, disabling OS dictation, reset preferences, swapped out for 24” 1080 dell generic monitors, etc.
I’ve tried to troubleshoot to the fullest extent. I honestly believe there is an issue with Illustrator at higher resolutions. Adobe, I hope you are listening because this issue has cause me (as IT) a huge headache, has everyone questioning the awesome gear I bought for them AND causing much frustration amongst all my artists. Many artists now have their unused/unplugged color calibrated, high-quality 32” 4K monitors collecting dust behind a crappy 24” generic monitor because of this issue.

Processor Speed: 2.3 GHz

I have the same problem here (Illustrator V 21.1.0) 64bit - Windows 10 pro
AMD Ryzen Threadripper 1920x
32 gb DDR4
RX 580 8gb DDR5 video
M2 Samsung SSD 970 EVO HDD
It all started when I upgraded my old ultra wide 2560x1080 monitor to a full 4k display.
On the native 4k resolution all zoom in/out operations with overprint preview on take 3-6 seconds and freezes the system.
If I change my monitor resolution to lower values(1920x1080 for example) everything is back to normal and working fast.
It seams all the problems are related to high resolution (4k and above) and is relative old problem.
If anyone found a fix for it can you please post it here because i could not find it.
Activating or not GPU performance at least in my system case does not have any impact over this bug
I just got a brand new iMac (iMac (Retina 5K, 27-inch, 2017) ) with illustrator CC all up to date and every time I put the overprint preview on, illustrator get very slow.
I recently try to get help from Adobe support team, but they could'nt fixe the issue! Anybody can look into this?
Also, the file size doesn't matter, whatever I try in a simple or more complex file the overprint preview always slow down illustrator greatly.
