And what about GPU

Illustrator needs to be relaunched with a fresh slate, new code, utilising the latest technology and multicore-ready. I'm using Affinity Designer more and more these days which tear Illustrator a new one in regards to speed of operation. Its only a matter of time before its matched feature for feature and Illustrator loses the race. Bored of waiting for simple things to be added... why no triangle in the shapes pallet, why are the shapes not live and active? Bored of seeing pointless new features shoehorned in over fixing and improving whats already here.

Let me add my voice to the chorus of multi-threading. One of the primary reasons most of us invested in higher-power multi-threaded compute platforms is for graphics work. For Adobe to be a decade behind the curve from a development perspective is unconscionable. I have a very nice 18-core machine that slices through video rendering in Final Cut Pro like a warm knife on soft butter, but I can wait 3 minutes for AI to apply the Torn Edges effect on a simple white rectangle. Silly indeed.

Honestly I feel like this should of happened awhile ago when multicore computers started coming out. It's a little frustrating when I'm sitting waiting for files to save and I can see that 90% of my computer's power is sitting idle and that only one core is being utilized. Sooo Much wasted time!

this indicates that since 2000, that is, from the moment of the invention of two-coreity, the code of the Illustrator kernel has not been corresponded... glory to developers forever and ever, amen!

slow software + slow work = longer period subscribers :D

This seems like a an obvious and overdue architectural improvement with CPU performance mostly skewed towards adding additional cores these days.

Oh, Adobe... Please put your resources into this. I know people(myself included) who have spent thousands and thousands on their system and still have to wait on the simplest of tasks. Just because illustrator uses less than 10% of the capacity. While software like e.g. Keyshot uses the cpu power for a 100% all the time, so you can actually build a system to meet your demands or at least, save you time.

We know you can do it, so please do

I'm currently hanging around waiting for Illustrator to finish embedding some linked AI files. I have a handful of other files open, but the whole app is locked up so I can't do anything else. It's using 10% CPU capacity (100% on one core). Crazy much?

In other news, I was one of those suckers who went for an Nvidia Quadro card based on all the marketing hype of 10X performance gains in Illustrator... more like constant instability and negative performance issues (and hours wasted experimenting with drivers)! I occasionally turn on so called "GPU Performance" again to see if anything has improved; not so far.

So yeah, multi threaded CPU functionality would be favourite in this day and age.

My goodness does this need to happen.. Nothing worse than buying an amazing piece of tech and having your software shut it down or have no way of using it.

I'm going to have to agree...
On a 8 core system it will consume on full load 12.5% (one core) and be sluggish.

On our 16-CPU render pc, it will use around 7% CPU (and be under full load) and be sluggish..

YES! PLEASE! It's way overdue for multi-core/multi-thread support.

oldie please catch up with your younger competitors cours plus vite

Agreed, when will we see multi-threading on Adobe apps.

I agree with this as well. I use Illustrator heavily throughout my workday, and I want it to be able to leverage the hardware on my computer better.

We also work with extremely complex compositions and it is so infuriating that there's no way to spec a machine to handle them. We have these exteremely powerful machines with extremely powerful CPUs, GPUs and huge amounts of RAM but AI is using a fraction of the power available. I appreciate this probably means re-writing half the program but surely a single-threaded codebase isn't sustainable in the long term as more and more features are added and user requirements become more and more demanding.

In terms of performance gains I would say GPU acceleration has helped our studio out somewhere in the region of 0%. Perhaps less as in a number of cases it has made the program slower and/or more unstable. These are new machines with modern nvidia graphics cards.

Our workflows revolve around AI, so this is probably the number one reason we don't fully embrace the Adobe ecosystem - we're hoping that at some point a competitor program will come along that matches the functionality but doesn't have these performance issues. It would make a world of difference! Even just to know that it was on the radar.

Agreed, this is an absolute must and fundamental considering the specs of even ordinary machines these days. For me, working on complex maps, this is the single biggest problem with Illustrator. In fact it has the worst performance of any app I use, yet the one I need to use most!! And please, don't lump the performance gains on the GPU, as for the most part this really isn't helping much.
