Awful Photoshop Lag on 4K Monitor (Here’s How I Fixed It)

I just bought a 4K monitor and I noticed Photoshop performed much laggier.

If I used to crop tool, I have to wait a split-second before the crop box moves. It’s jittery and stuttery, unlike on my 1080p monitor where it was butter smooth.

I tried everything they suggested online, such as disabling vertical sync and stuff.

Nope.

What worked for me was to Disable Native Canvas.

Here’s a video that shows you the problem, how to fix it, and the results.

Go to Edit>Preferences>Technology Previews>Disable Native Canvas and then restart Photoshop

You should have a much more responsive Photoshop.
