Camera RAW 14.0.1 brushes lagging with Macbook Air M1

Report · Nov 25, 2021

I am having trouble with a terrible lag on the brushes in Adobe Camera RAW 14.0.1, Up to 5-10 seconds pass before the brush effect slowly follows the action of the brush movement

I have a Macbook Air M1 with 16GB ram

Performance is set to auto

Hi Paul,

We're sorry about the trouble with Camera Raw. Could you please try updating Camera Raw to 14.1 and check if that makes any differences?

Try resetting the preferences of Camera Raw by following steps:-

Hold down the Command key and select Photoshop > Preferences > Camera Raw (macOS).
Click Yes in the dialog that asks "Delete the Camera Raw Preferences?"

Note: Please backup the preferences before resetting by going to the location Users/[user name]/Library/Preferences and then you will see Adobe Camera Raw [version] Prefs.

Let us know if that helps.

Regards,

Tarun

Thank you for your response,

I did update to Camera Raw 12.1 and cleared the preferences. Problem persists. I disconnected the 4K Dell display and restarted photoshop, the problem persists.

Thanks for trying the steps.

Please try turning off the GPU in Camera Raw and let us know if that helps. You may also check this article for more information: https://helpx.adobe.com/camera-raw/kb/acr-gpu-faq.html

Hi thank you for your response. I am still plagued with inconsistent behaviour.. If I make an adjustment, say turning off the GPU.. I get a slowdown in other areas.. such as scrolling around the image, or if I move the image with the hand, it doesn't stop moving when I let go.

How do I get rid of all preferences everywhere? Bridge, photoshop, lightroom classic...

thank you

In the Camera Raw Preferences in the Performance section, try setting the Graphics Processor option to Custom instead of "Off." The Custom option reveals some checkboxes. Try turning off "Use GPU for image processing" but leaving "Use GPU for display" turned on. Using the GPU for display accelerates with the GPU the final drawing operations used for zooming, panning, etc., where as "image processing" uses the GPU for rendering the effects of the settings, brush strokes etc. before the photos is finally displayed on your screen.

You will find the same set of Graphics Processor options (ie, the same Custom option and checkboxes) in Lightroom and Lighroom Classic; they can be configured independently of the Camera Raw plugin. GPU related options you find in the Preference dialogs of Photoshop and Bridge are not related to the Camera Raw preferences at all.

When you see the slow "brushing" are you talking about the healing brush or the masking brush, or both? Do you see the same slow brushing performance in both Lightroom and Camera Raw (with the "auto" option?). Also, can you tell me what workflow options you are using in Camera Raw (what color space, bit-depth, other options). Click the underlined text below the photo in Camera Raw to open the Workflow Options dialog.

Thanks for your patience,
David

Thank you so much for your generous reply. I gave up using the healing brush a few generations ago, seeing as it was a cumulative lag that would build up with each new retouch point, so I haven't noticed whether this issue is affecting that function. My experience of the slow brush has been limited to the masking brush with this version of Camera Raw plugin. Colour space is Adobe RGB 1998, 8 bit.

With the same images, and the same performance settings i.e. Custom performance settings, with only use GPU for display activated, there is no lag that I can see in Lightroom Classic 11.1

thank you,

Can you tell me if your M1 MacBook Air is a 7-core GPU model or an 8-core GPU model?

Thanks,

David

if i turn off the graphic acceleration , i can use the brush (still slower than before), but the other function becomes very laggy.
