Forcing Lightroom to work with OpenGL on Windows 11

Hi, I need help please.

I'm using Lightroom Classic 12.5 with Camera RAW 15.5, on Windows 11.

My GPU is ASRock Phantom Gaming Radeon RX 6950 XT.

My CPU is AMD Ryzen 9 5950x and I have 80 GB of RAM installed.

All my drivers are up to date, including Windows update.

My camera is Sony A7R V, and I'm editing RAW (.ARW) files weighing about 120 MB each.

I'm experiencing repeated freezing while editing photos. Lightroom becomes unresponsive for 5-20 seconds every few minutes. Between freezing, it works just fine. It does not crash.

On Edit > Preferences > Performance, 'Full graphic acceleration' is enabled.

Under 'System info' it shows Lighroom is using DirectX (and not OpenGL).

If I disable 'Use GPU for image processing', and use my CPU for processing, I don't encounter freezing.

I have read that forcing Lightroom to use GPU with OpenGL instead of DirectX can possibly resolve this issue, but I couldn't find any way to change that setting under Windows (only Mac, using a modifies config.lua file).

Does anyone know how is it possible to change this setting? Any other suggestion will be appreciated.

Thank you.

I have solved the problem. It was because I've used a slow and old SSD.

Ya. I too bought a new NVM.2 but still have the issues.

Why don't AMD find the solution for this issue? If it Turns off the GPU Acceleration Lightroom working without issues. My question is " If we are going to work without GPU support Why do we spend this much money on AMD(RX) GPU?

I have noticed lots of issues with AMD GPU and adope products. A lot of users crying in the AMD Community.

Why is your CACHE limited to 7GB? Adobe recommends increasing that to at least 20GB.

Update: I found that under prefrences > performance, pressing the 'Purge cache' for both camera RAW and video improves performace and freezing occurs much less.

Could it be a faulty SSD that cauuse the problem? (Pictures are storaged on a new SSD but the software itself, Windows, and the cache are on an older SSD)

Adrenalin or PRO edition? Not a AMD user, so my driver knowledge a bit iffy, but it looks like, for the Adrenalin, a newer version is available (Windows release 31.0.21031.1005)

I have tried both Adrenalin and Pro drivers, both had the same problem. Now updating to the newest adrenalin driver. Idoubt it will make a difference.

Thanks

The camera make/model in that path makes me ask, is that path pointing to the camera, or a card in the camera, as opposed to a hard drive?

There's no solution there...

It shouldn't exist, you'll need to create it if needed.

As for how to force OpenGL - you wrote that you know how to do it on Mac.

On Windows it would be the same.

Maybe this will help:

I have no idea whether it will work for modern LrC versions or not.

Thanks. I've already followed this youtube guide and palce the config.lua file in the correct location - but it made no change on Lighroom. It still uses DirectX and not OpenGL, and freezing still occurs.

Thanks, but it doesn't exist in my folder in the path you specifies, and it doesn't answer my question how to make Lightroom work with OpenGL.

Hi.

config.lua is Lightroom Classic config file and has nothing to do with MacOS.

Its path:

On Windows:

C:\Users\<Username>\AppData\Roaming\Adobe\Lightroom\config.lua

On MacOS:

~/Library/Application Support/Adobe/Lightroom/config.lua

Settings inside this config file are OS independent for the most part.

Adrenalin or PRO edition? Not a AMD user, so my driver knowledge a bit iffy, but it looks like, for the Adrenalin, a newer version is available (Windows release 31.0.21031.1005)
