Switching tools, ctrl-z, zooming, using the click-drag for the hand tool (shifting the canvas), and using the eraser tool causes Photoshop to lag and sometimes to freeze. Brush tool usually works fine but sometimes has some lag if I have just done one of the items above. This has been happening since I switched to a new laptop and started using it with an old Wacom Cintiq (approx 10 years old).
Processor: IntelCore i7-8850H CPU @2.60GHz 2.59 GHz
Installed memory (RAM): 32.0 GB (31.6 GB usable)
475GB SSD with 163GB free
When I check the CPU and Memory usage while I'm using Photoshop, the CPU usage never goes over 5% and the memory usage never goes over 22% even though Photoshop is lagging and freezing. Plus, I have recently noticed that there is a difference between using the trackpad and built-in laptop keyboard versus the cintiq and a USB keyboard.
It's a new Lenovo Thinkpad P52, so it should be able to handle Photoshop. It handles Premiere just fine. I'm using it with a Wacom Cintiq 12WX (DTZ 1200w), sometimes an old Wacom Bamboo as well. Does multi-Wacom use cause problems? Or the age of the wacom? It does not have problems with other programs (e.g., it works fine on Premiere).
I also create and use most of my files within a Dropbox folder, but Dropbox should only interfere with saving -- and the files never have problems saving.
I'm at a lost! I've tried reseting the preferences, unchecking "use graphics processor", checking it again, letting photoshop use more RAM, increasing the cache levels, decreasing the cache levels, decreasing the history states... I'm not sure what else to do!!
Any tips or advice??
Crash or freeze, Performance, Problem or error, Windows
We are sorry about the performance issues with Photoshop on your Windows computer.
Would you mind confirming if you experience the lag while using the the trackpad and keyboard of your laptop as well or is that noticeably faster? The age of the Wacom tablet should not have a major impact on the performance nor should using multiple tablets unless the Wacom drivers are outdated. You can try to install the latest drivers for the Wacom tablets and check if that helps. It might help to perform a clean up of the Wacom drivers and install them from scratch.
I'm having a similar problem with the brush tool lagging or completely freezing after switching between tools with Photoshop 21.2.6. The only workaround I've found is to close the image and reopen (I don't have to reboot PS), which is really slowing me down.
I've updated Windows, removed and reinstalled Wacom driver, removed and reinstalled Photoshop (I started with the most recent version of PS and had even more problems), and disabled Windows Ink, but nothing has helped.
