Denoise AI suddenly very slow
Hi,
I’m having a problem with Adobe Lightroom on Windows.
Until recently, the AI Denoise feature worked very quickly for me — processing one nature/wildlife photo usually took only a few seconds.
Now, the same process takes around 3–7 minutes per photo. What’s strange is that Lightroom often shows an estimated remaining time of only 9 seconds, but the actual processing continues for much longer.
Nothing has changed in the way I use the feature, and I’m processing similar RAW files as before.
Could anyone help me figure out what might be causing this?
I would especially like to know if this could be related to:
- GPU acceleration
- a recent Lightroom update
- NVIDIA/AMD graphics driver issues
- Lightroom cache or preferences
- Windows or GPU performance settings
I’m using Windows.
Any advice on what settings I should check or how I can diagnose whether Lightroom is actually using my GPU for AI Denoise would be greatly appreciated.
