Laggy Mouse When Photoshop Is Open

[TheChancellor]

My cursor lags (slow, jumpy, sporadic, etc) a massive amount in Illustrator, as well as InDesign when Photoshop is open. I use all 3 programs everyday and interchange between them most of the day. The cursor lags primarily over the work area in both programs, however when you hover over the toolbars it works completely fine. Same case when you hold space to move the art-board around the cursor works fine. I've had this issue for months and wish there was a fix by now. It makes the other programs virtually unusable. I have to save my Photoshop file, close it out, work in Illustrator, then open Photoshop back up whenever I'm ready to transfer something. Does anyone have any ideas how to fix this? All apps are up to date and computer is up to date.

Sounds like an underpowered computer.

Does your computer have sufficient resources to run Creative Cloud + Photoshop + InDesign + Illustrator + your operating system + all your other utilities & services at the same time?

Try shutting down all non-essential processes and adding some extra RAM memory.

Nancy,

I feel like I have enough power to handle those, my fans hardly ever kick on. Here's more specific specs:

2.5 GHz Intel Core i7

16 GB 2133 MHz LPDDr3

I would think I have enough ram to run them at the same time, correct? Like I said, it's only on the art-board, no where else throughout the program, thats what makes me think its a software issue?

PS, AI and ID are major resource hogs.  And Mojave doesn't help matters.

I'll look into those tips, thank you! Its currently lagging in Illustrator with just Photoshop open and my CPU load is currently at 9%. So that wouldn't explain it lagging just in the art-board I wouldn't think. In Photoshop my cursor is completely fine, its just specifically in Illustrator or Indesign.
