Photoshop running slow and lagging when you edit photos
Photoshop runs out of memory when editing. Go to Edit > Preferences > Performance and increase your allocated memory and GPU resources. This fixes it for most people in under 5 minutes.
Photoshop needs memory and graphics power to process your edits in real time. When you don't give it enough resources, every brush stroke and filter takes forever. Telling Photoshop to use more of your computer's resources fixes the lag.

Skip — I just want a technicianCommon mistakes to avoid
- Not restarting Photoshop after changing memory settings
- Not realizing that your operating system needs memory too
- Setting memory allocation too high (above 90%), which can cause crashes
- Not checking if GPU is enabled before assuming it's a memory issue
Signs you need professional help
- If you've increased memory allocation to 80%, enabled GPU acceleration, and Photoshop is still laggy, your computer may not have enough RAM for the files you're working with.
