Denoise won't complete

I also get the "unknown error, denoise was not applied" message, and then a message saying "due to a run-time error the GPU has been disabled for the remainder of the session."  Unfortunately, I don't see how to use the previous discussion of this.

I am running Win 10 on a laptop and using LR Classic. I use a single catalog, the latest version of Classic, and (Windows says) the "best video driver" for the device.  The following is the GPU description:

"Nvidia's RTX 3060 is one of the best graphics cards for mid-range performance — armed with 3,840 CUDA cores, 6GB GDDR6 video memory, and a boost clock speed of up to 1,703 MHz."

 

Denoise goes through all the motions of loading data and previewing the enhanced photo but then fails and shuts down the graphics processor as well.  (I am not aware of any other problems with the GPU.)

Is there any further information I could provide to help get a solution to this issue?

TY.

Windows wouldn't have a clue about whether you have the "best video driver".

 

Go to the Nvidia website (or use the Nvidia app on your machine) and make sure you have the latest stable driver, from the horse's mouth.

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.

Laptops are particularly troublesome in the GPU department, because most of them have two - a dedicated high-performance GPU, and another integrated in the CPU. The problem is that they tend to conflict.

 

Dual GPUs work fine for simple applications that just send data one way downstream - but Lightroom and Photoshop use the GPU for actual data processing, and the result returned to the application for further processing. There can only be one GPU in that equation. You can't send data to one GPU and get it back from the other.

 

In addition, laptop vendors frequently modify and tweak GPU drivers for various purposes.

 

This is a very common problem with laptops. Desktop systems don't have this problem. Often you may need to completely disable the integrated GPU, so that the "proper" GPU can do its job.

      That was easier said than done (don't ask), but it was the answer.
      I'd like to mark it as the correct answer but don't see a link to do that.
      In any case, thanks much for the help.
