Illustrator incredibly slow new iMac 5k 27" 2017

Illustrator is incompatible on 5K screens, you work very slowly, you contract, you wait in front of it. If the Adobe team installs ai cc with Imac 5K and tries it, they will see the problem. But they persistently ignore this problem and the complaints. I repeat, the ai cc is problematic on 5K displays. 2020 imac 5K has serious performance problems with all computers, if you want 128 gb ram, 32 gb graphics card, it will still run very very slow. You can see the difference by installing the application called QuickRes and choosing 2560x1440 non-HiDPI resolution instead of 2560x1440 HiDPI.When HiDPI is active, it slows down as if using ai cc virtual machine ... If you cannot get 5K imac, I can borrow it ... Hear my voice adobe ...

This was marked as solved, so what's the answer? How does one person contacting customer support help the rest of us with the exact same situation? What did customer support do to fix the problem, if anything?

I have an Imac 5k, brand new, brand new illustrator installed, completely unusable. Takes 6 seconds or more to make a point with the beizer pen tool, dropdowns menues take several seconds to appear, etc etc.

hi, someone found the solution to this problem? I have an iMac 5K Middle 2018 27 "and not even the latest version of Illustrator works well.

I seem to have found a temporary solution, the problem is adobe's poor optimization for HiDPi scaling on Mac, right click the program -> get info -> check "open in lower resolution" Has seemed to fix it, but text and the interface isnt as sharp as before. Adobe please fix.

I have a Dell computer and Windows system, my Illustrator has just suddenly in the past week become frustratingly slow. Very small vector files take forever to save or export as PDF, I literally have to find something else to do while it's saving otherwise I waste time and will go insane.

If you have recently updated Illustrator to CC 2018 but have retained your previous preference files then that may be the cause of your slow performance. It has proven to be the case for many users.
