brush lag on new layers - Photoshop CC

  • Updated 4 years ago
Got a pretty frustrating issue that's made photoshop un-useable as of late. It wasn't happening at first but now it won't go away.

I can only draw on the background. When I make a new layer, short strokes lag horribly to the point where I can't draw at all. Making one long line doesn't get any lag.

I've tried a few different fixes but none have worked. I've not changed any hardware and it worked before. Does anyone have any suggestions?

Have you installed all the Photoshop CC updates?
You should be on version 15.1, aka CC 2014.1.

Thanks for the quick reply! Updated the original CC and still had the issue then tried the new Photoshop CC 2014 version but it's worse.

I don't know if it's related but opening a new blank document and making a new layer take relatively longer than before there were any problems.

The brush lag also happens with both mouse and graphics tablet.

Here's some things I've tried in a list:

- Does it with any preset brush/custom brush. Size and spacing have no effect.
- Document size makes no difference.
- With/Without charger plugged in
- Affects mouse and graphics tablet
- Only on new layers. Background layer is unaffected.
- With "Use Graphics Processor" on, it still happens under "Advanced", "Normal" and "Basic" modes. Happens with the graphics processor off as well.
- Tried using between 50% and 100% RAM but made no difference.
- I don't have multiple displays which seemed to be the culprit for a few people.
- Graphics drivers and Tablet drivers are up-to-date
- If I try to click elsewhere while it's making the brush marks it doesn't stop responding like I'd expect it. It keeps the brush cursor and doesn't let me do anything else though.

Not sure if it's related but here's other issues that have cropped up:

- Making new layers and deleting new layers is slow.
- Opening a new document is really slow
- Drop down menus seem choppy as if the PC is struggling?

I watched Resource Monitor while using menu, making new layer, drawing etc and my CPU and RAM usage stay about the same. I've also tried making loads of brush movements then swapping and using Firefox to see if either program has a fit but Firefox is fine and even photoshop doesn't freak out and start being unresponsive.

My specs are:

Windows 7 64x
Intel(R) Core i7 CPU Q 720 @ 1.60GHz
4GB RAM
Nvidia Geforce GTX 260M

I know 4gb RAM isn't perfect for PS but it worked before.

Hello again!

My Photoshop seems to have pulled itself back together! :) I cleared all my temporary files and such using Windows' disk clean up and it seems there's no lag now.
