Thanks for reaching out. We are sorry for the trouble with Photoshop. We are here to help.
Could you please share the version of the operating system you are working on? Are you experiencing the lag during any specific task, using any tools, or operations? Are there any specific documents that lag, or were Photoshop 23.2.1 lagging generally? Does the lag happen on
If you have experienced this on the first launch? It could be because of carrying forward older preferences. You can install Photoshop 2022 again and reset Photoshop's preferences to give it a fresh start.
Once Photoshop 2022 is installed, and you have launched it at least once, you can close it & then go to the location of the preference folder mentioned below.
