My Lightroom cannot turn on the GPU full graphics acceleration function. Currently, only basic graphics acceleration can be used, and "Use GPU to process images" cannot be checked. How can I turn it on?

Thank you for your reply, I just confirmed that the AMD driver version is 22.3.1 (released on 2022/03/09), but still cannot enable full graphics acceleration

Thanks for your reply!
I did the following according to the website you provided:
1. Use DDU and remove the previous NVIDIA graphics card driver (1050Ti) and AMD RX6600XT driver in safe mode
2. Reinstall the RX6600XT driver (version 22.3.1) using "AMD Software꞉ Adrenalin Edition"
3. Lightroom still cannot turn on full acceleration, decided to remove Lightroom and reinstall it
4. Open Lightroom again, but still cannot enable GPU acceleration for image processing

"NVIDIA graphics card driver (1050Ti)"

 

I did not see this GPU lsied in the System Infor you posted. This may be causing the issue. LrC can use two GPUs, but it does not increase performance. What GPU do you have the two displays connected to? See the below article.

 

https://helpx.adobe.com/lightroom-classic/kb/lightroom-gpu-faq.html

 

  • Lightroom Classic currently doesn't take advantage of more than one graphics processor. Using two video adapters does not enhance performance. To resolve issues arising because of conflicting graphics drivers, follow Step 5 and Step 6 in Solution 4: GPU and graphics driver troubleshooting steps.
  • Only the 'Main' Lightroom Classic window is accelerated. The 'Secondary' window isn't accelerated by the graphics processor.
  • Graphics processors running under virtual machines are not tested or supported.
  • When you launch Lightroom Classic, it runs a test on the graphics card. If the test fails, the graphics card is disabled even if it meets the minimum requirements. Walk through the troubleshooting steps to try to resolve the error. Some graphics cards, despite meeting the minimum requirements, may never be compatible with Lightroom Classic for graphics acceleration.

 

Two things to try.

 

1) Use only the AMD RX 6600 XT with both displays plugged into it and none into the Nvidia 1050 Ti.

 

2) If that works do a clean install of the latest Nvidia 1050 Ti Studio driver 511.65.

Sorry for the misunderstanding.

 

Before replacing the AMD RX6600XT, I was using the NVIDIA 1050Ti graphics card.

The above description is only to express that I have used DDU to clear all the display drivers that have been installed on this computer, and then follow the instructions on the website to install the latest version of the AMD graphics card driver.

 

The computer has only one AMD RX6600XT graphics card.

 

sorry again, thank you

Hi, sorry to just jump in like this, but I might have the same problem. Difference is, I'm using a 6900xt. Checking the Camera Raw GPU logs, I found out that my GPU seems to fail the accelerated render quality test.

This is the end of the log output:

Begin cr_gpu_test::RunSanity (quick = False, doing init = True).
Bounds of image A are: 1000 and 1000
Bounds of image B are: 1000 and 1000

Does this problem still persist for you? If so, mind checking the logs in

C:\Users\*your pc username here*\AppData\Roaming\Adobe\CameraRaw\Logs

to see if you have the same error?

I'm pretty sure it's also in the part that I posted. I should have clarified that the attached log is indeed from the "Lightroom Classic Log Latest v1.txt", unless you are talking about something else:

After the cr_sdk_terminate the file ends
