Brushing slows down in CS6, Mac OSX 10.6, Wacom tablet

  • Problem
  • Updated 4 years ago
MacPro,12 GB RAM, OS X 10.6.8, Photoshop CS6, Wacom Graphite pen tablet: I have a large file with several photos stacked on each other. I made a black layer mask on the top pixel layer, and started brushing small areas (while viewing at 200%) to see the layer below. The brush starts off fine, but within a minute gets sluggish, and then continues to get more and more sluggish. After 5 minutes it takes the display a second or 2 to catch up with my brush moves. The brush really needs to have real time feedback. I stop brushing, save the file, close Photoshop, restart Photoshop, and start brushing again. As before, it starts off fine, then quickly degrades. So my project has slowed to a crawl. I've never seen this problem before. I found a closely related issue at http://forums.adobe.com/message/4649117 . HELP!

Can you confirm you've updated to 13.0.1? Any other applications (like Bridge) running at the same time? If so then I have some things I'd like you to try.

Thanks,
Adam

Adam - thanks for replying. I still have the problem after installing 13.0.1. No other apps are open except Finder.

Two things to try: lower the amount of RAM available to PS (to something really low like 3GB - in Preferences > Performance... - remember to restart the app after making changes) and try changing the tile size to 128K instead of 1024K. Does either change help with the issue you're seeing?

I switched to CS5 and do not have the problem! There must be a bug in CS6.

1st. set PS RAM to use 70%

2nd. what video card and video card settings in prefs? try disabling GPU acceleration or put on basic.

3rd. definitely limit anything that could be using Flash.

4th. Is the graphire an older tablet? Makes sure the Wacom driver is updated.

I'll check for Wacom updates. It runs great in CS5 so I have to think there's a bug in CS6.

but brushing in CS5 and CS6 are great on my systems.
so it could be your system. i really think its video card related. you haven't given us that info. thats definitely a big part of it.

The latest info on this is that the problem occurred on a specific image, but not on others! Adobe Tech Support is researching the problem with the assumption it might be a bug in CS6. In the meantime I'm using CS5 which works fine on this and all other images.

The video card is an NVIDIA GeForce 8800 GT.

Can you email a copy of that image (or a URL to it) to Adam or myself?

ZIP it and see how big it is then. If it's still over 100 Meg, consider something like Dropbox or Google drive. Worst case, email us and we'll work something out.

Chris - I had to keep working this photo over the weekend, and it is now a GB. Can I FTP it to you at some Adobe FTP site?

A Gig file won't even FTP well. Can you simplify the file to something that still fails? (duplicate the file, open, remove groups, save, open, test to see if it still fails, repeat)

I too am having this problem. It's not file specific. After working on files for awhile PS CS6 starts crawling when I erase. I mainly notice when erasing on a top level layer.

I have to restart my Mac and it works normally for awhile... I never noticed this in previous versions. Right now as I write this it has had one of these "attacks"... sometimes it takes 3 - 5 mins to allow me to do anything. So I will quit and restart my Mac now. I'm using v13.0 64x. I notice there is an upgrade... I just tried it and got this error message:

"Photoshop 13.0.1 update for Photoshop CS6 and Photoshop CS6 Extended
There was an error installing this update. Please quit and try again later. Error Code: U44M1I200"

Will try again.

Restarting Photoshop will clear all of Photoshop's state.

Having to restart the machine means that there is something else going on outside of Photoshop (like bugs in antivirus software, or a driver problem).

Which OS version are you using?

I get these slow downs here and there - and my machine is well spec'd and maintained. I have narrowed it down to having flash sites running in Chrome in the bkgd. Everytime shutting down chrome, maybe using another browser for things like Google play or Pandora - PS is fine. I would never switch away from Chrome (b/c everything syncs w/ my Android devices) but I think it has flash player issues. Not the end of the world for me, since I can shut down Chrome and work normally when it gets bogged down. I'm using a 2009 Mac Pro, 16GB RAM, 10.6.8, etc. It would be nice if they could figure it out but I'm sure its low on the priority list now.

We're still trying - but so far we can't reproduce it.

But Chrome and Flash do seem to be pretty common issues.

I found that when I play video on Chrome, Photoshop become slow. No problem when I do the same thing using Safari. (MacPro 5,1 3.2 GHz Quad-Core 48 GB RAM, Startup disk = RAID 0 2x SSD Accelsior, Photoshop CC 2014)

Chris - I've had a very heavy workload and out-of-town travel, so haven't gotten back to you.

Chrome and Flash were not being used while I was working the photo.

I thought the problem was just with one particular file, but I started having it with another file, and just switched over to CS5 to continue production work.

I'm prepared to send the specific file that showed the problem if you can advise how to do so, given that it is so large. I could cut you a DVD if necessary.

Chris - I'm having the same problem now on another large file with 30 layers, where I'm brushing on a mask.

And I'm having no problem with the same file and activity under CS5.
