Camera Raw requires GPU acceleration to edit photo

[neil_4506]

Out of the blue I can't edit my Raw images in Camera Raw. I have a 2023 imac with an updated OS. Why is this happening. Last week I was good? see attached screenshots

First thing to try is #6 from here:

6. Check and delete the TempDisableGPU3 or TempDisableGPU2 files

Jeff thanks for chiming in and I'm not sure what or where TempDisableGPU3 or 2 is.

[neil_4506]

any other suggestions?   ____  thanks ~nd

Neil, Jeff's post is apt; the entire (GPU) FAQ and troubleshooting page is loaded with important tips.

How does this screen look?

[neil_4506]

that page is filled with alot of things I'm not familiar with... foreign language type stuff!

That screenshot is pretty telling Neil!

Use Graphics Processor is grayed out, cannot be opened so as to turn on; 

"Camera Raw graphics acceleration is not supported by your system."

What happened in the time since you were able to edit in Camera Raw?

btw, I hate random or sporadic error messages -- I got an error message a few months ago, ignored it, never saw it again. Well, it's baaack. "Lightroom Classic does not have access to some Standard folders." How less-than-helpful.... "some"? why aren't they named? "Standard"? What is standard about the folders?

Not your issue, Neil, and I broke my promise to not complicate a fellow user's post. But my issue is sort of related -- what used to work quit, without explanation.

[neil_4506]

I don't think anything has happened... no updates or anything like that! It was fine the week before now its not?

Neil, your original post's screenshot  (July 18) shows that the GPU is detected. But July 19's screenshot shows "Camera Raw graphics acceleration is not supported by your system."

Please take time to read everything on the webpage Jeff posted, especially sections

• GPU requirement for photo editing 

"If GPU support is disabled, you may be able to allow support by taking these actions:"

• Camera Raw's GPU settings with other applications
  [this section explains better than I can -- "GPU related settings in Camera Raw do not change when you switch on or off the GPU related settings in Photoshop, Bridge, or other applications. Conversely, GPU related settings in Camera Raw do not affect other associated applications...."
  I interpret that to say GPU works *if turned on for the application you are currently using*. to that end:]
• Determine if Camera Raw is accessing the GPU [in Ps and Bridge]
• GPU troubleshooting steps for Camera Raw and Lightroom

Jeff's Step #6 has flashing lights for me.

"If an unhandled, fatal error occurs during GPU initialization, Camera Raw or Lightroom leaves behind a TempDisableGPU3 file (or TempDisableGPU2 in some cases). In the GPU folder, find the subfolder for the application you are using and check for these files....

If a TempDisableGPU2 or TempDisableGPU3 file exists at initialization time, Camera Raw will disable GPU acceleration. This prevents the app from crashing, each time you launch the application.

You can delete the file to run initialization again. If the original failure condition is transient, GPU acceleration may work correctly after deleting the file."

Your "up to bat," Neil!  😉

thank you for taking your time helping me figure this out! I'm all set now.

I have run into this error before on my Mac. Maybe a few screenshots will help:

Open a Finder window, and from the Go menu, select Go to Folder...

In the dialog that opens, type or select-copy-paste this path in:  ~/Library/Application Support/Adobe/CameraRaw/GPU/Adobe Photoshop Camera Raw/  (That curvy dash is called a tilde and is shorthand for your User directory.)  Press the Enter key.

This will open the correct directory where you should see the GPU2 or Gpu3 file. Delete it and re-open Adobe Camera Raw.  The GPU error dialog will be gone and ACR should be back to normal.

THANK YOU, THANK YOU, THANK YOU!!!!!!!!!

Screenshots were so awesome!

Thanks for reporting back. Since this answer got results for you, I'll consider it a correct answer and mark it so perhaps it will help others with the same problem.
