Any one seeing lag with the smudge tool in CS6?

Mar 23, 2012 10:14 PM

the smudge tool seems to be dragging hard in CS6 beta with the same tool preset and file that i was using in CS5, while all the other brushes and tools seem snappier if anything?

    Yes, I see that too.  Quite a slow motion response I'd say.  One single stroke with a modest sized brush hasn't finished in all the time I'm typing this.

     

    It does keep up better with quite small brushes.

    For troubleshooting sake: is it the case with all settings? Noel reports smaller lags with smaller brushes (which is to be expected, but useful to report)

    16 bits or 8 bits, etc?

    8 bit and 16 bit images. brush size over 80-100 pixel are very slow on a 8bit 2000x2000 pixel image.

     

    CS5 is much faster for the same brush size, even on bigger (5D MK2) 16bit images.

    i would check your GPU settings in the performance prefs. I have mine set to Basic always. seems best for my computers.

    Might be nice to hear from some of the Adobe folks on this.  Performance for the Smudge Tool definitely seems down from CS5, though it's not unusable for small things.

    I find no significant difference with either blur or smudge. CS6 allows for larger brush sizes than CS5. COuld that be the problem?

    as i wrote,.. 80 pixel are not a huge brush size.

    Sorry I missed your note about the brush size. I agree, those are actually small brush sizes. I start to notice a lag when I am up to 1000 px. Possibly a video board issue? I think CS6 makes more extensive use of video memory.

     


    Not with blur and sharpen, but I did notice an increasing lag time using dodge and burn after opening and saving many different images. A reboot solved it making me think there could be a memory leak issue. Perhaps the same with smudge?

    Are all of you using a pen and drawing tablet or a mouse?

     

    Thanks,

    For folks that are encountering this, what is the Cache Tile Size set to? (Prefs/Performance pane) Does setting tile size to 128 inprove performance at all?

    Yes, changing the Tile Size to 128 removed the lag for me.

    I'm using a Wacom Intuous 4 when I notice the lag. I first thought it was only dodge and burn (since that's usually the last steps in my workflow) but it happens with the healing brushes too. I seldom use sharpen, blur or smear so I can't comment.

     

     

    As a Duh! moment, I'm going to check my Wacom driver. I remeber having problems with the tablet installation, and still some apps (like Xrite i1) don't detect the Wacom mouse.

    Hi M Shaw,

     

    My Cache et. al. were set as follows and I could easily reproduce the issue on Photoshop CS5.

     

    PerformanceSettings.jpg

     

    Changing to 128K made no difference.  The tool just crawls.  I'm not sure this is a new issue.

     

    I'm running PS CS6 on a VMware virtual machine with the AllowOldGPUs tweak, so I have some rudimentary GPU acceleration, but I'm about to install Photoshop CS6 on my main workstation.  I'll report back...

     

    -Noel

    Changing to 128 didn’t change the performance  for me.

    Just so we're managing expectations here...

     

    I select the Smudge (finger) Tool.  Set it to 100 pixels, fuzzy-edged brush, 50% strength.

     

    On a 16 bits/channel image 1500 x 600 pixels and 2 layers, dragging the tool from corner to corner takes:

     

    • 3 seconds with Sample All Layers turned off.
    • 6 seconds with Sample All Layers turned on.

     

    The timing is just the same in PS CS5 and CS6.  So I'm not seeing any kind of new problem.

     

    The effect is so smooth I'm thinking this is just the computational overhead of doing the Smudge operation all in the CPU.

     

    -Noel

    1.1 seconds and 1.6 seconds.  Shift clicking from one corner to the other, and tried five times each to check for stop watch errors.  (It was coming out within a tenth second each time).    I wondered of lots layers would make a difference, but it seemed not to.

     

    It's 3:00pm here, and I have not done a stroke of proper work today, and I have a two day deadline, but no motivation.    The sun is shining.  The harvesters are out there scooping up grapes, (THIS was shot about 100 metres from where I am sitting, but back in 2008).  and I have just started the latest Vince Flynn book on my Kindle.   If only I didn't feel so bad about it.

    If it's Photoshop work you have to do, then I can't imagine how you're not looking for things to stretch CS6's legs out with.

    Yes, with the smudge tool and with ordinary brushes as well. I have no way of measuring if it is worse than previous versions--but it certainly isn't better. And this happens even with relatively small brushes, especially when doing one stroke after the other (like in drawing in or smudging hair strands). It's make a few strokes, pause for the moving hoop, do a few more strokes, pause again, etc.

     

    I find it strange because for other  functions this version is noticeably faster. I've just opened a 3.65 GB file in the time it used to take to open a regular 60MB file before. I've never seen this type of speed before. But when it comes to brush strokes--with any tool and any size brush--I'm very disappointed.

     

    I have more than enough memory (12GB RAM) and an NVidea video card that should be able to handle more. I don't think the trouble is with my system, I think it is a feature that wasn't optimized for this version.
