This is a new issue, I didn't notice until I realized my computer was working working.

 

The GPU custom for images processing is grayed out.  Anyone know why?

It just means that the graphics processor isn't  compatible, and is disabled automatically. Don't worry about it. My computer has on board graphics, no graphics card, and it's disabled as well. If your computer is working fine then just keep using it.

That's really all I can tell you. With a computer that's five years old, and doesn't have a 4K monitor, it's highly unlikely that you would see any real benefit from having GPU support anyway. My computer is even older than yours, and I get along just fine without any GPU acceleration. You could try checking to see if they are are any updated drivers that might change things, but I suspect not. I don't have GPU support myself so I can't give you any more information.

I process RAW files.  So seems a real issue or a bug since this is a new issue.  Alright will look else where or wait for more guidance.

 

Graciously,

Gary

I'm sorry, but what does processing raw images have to do with anything in this discussion? That's all I take, and my computer and Lightroom Classic handles the images just fine. But you can spend the next several weeks trying to resolve the issue. I hope you find something that satisfies you. If the GPU is disabled, and you can't find drivers to resolve that, then either replace your graphics card, get a new computer with better graphics, or just don't worry about it.

Just clarifying what I use my computer for.

Yea, I'll continue to look thank you.  Seems odd to all the sudden not be working with the designated GPU on board.  Its been only a recent issue.  I was able to choose it recently.  I have seen Adobe have system issues often.

Adobe probably decided that the GPU in question was not as compatable as previously thought, and changed the code in LrC to treat that GPU as not supported. Now this could occur at an update. 

 

Note that most system reqquirements listed by Adobe are minimal, so unless the system requirement is for GPU acceleration to work, then it msy be for just LrC to function.

 

Note that Adobe appears to poorly update such documents.

Try the following. Close Lightroom. Browse to the Library folder inside your home folder, go to Application Support/Adobe/Camera Raw/GPU/. Delete the Camera Raw GPU config file you find there and the one in the Lightroom CLassic sub folder.

Restart Classic and check the performance tab. Did it revert to being supported in Auto?

There was a relatively significant change to GPU in LrC 8.4 update which made some Graphics Cards not fully compatible and I believe you may have been affected. See my post in the thread you posted in earlier today the link is posted for easy reference.

The answer is I spoke with Adobe.

 

There appears to be a slight misinterpretation with the wording in Lr.  When “auto” is chosen, it says “basic” acceleration is enabled.  However, when in Ps, advanced is enabled.

 

Before the change I used the manual way with custom.  But this feature doesn’t seem to be enabled in the current version of Lr.

 

The list of compatible GPUs does list the one in my machine.  Plus, the additional checking via Ps reveals this.

 

So, the answer is use “auto” in Lr for now until they return the feature of custom.

 

Grace and peace.
