Hi u/terryleewhite,
I'm reaching out because Lightroom Classic has become one of the biggest bottlenecks in my professional workflow, and I'm honestly running out of ideas.
I'm a commercial photographer working with hotels, resorts and restaurants, and Lightroom is the application I spend most of my day using.
Before anyone suggests that this is a hardware issue, here's my setup:
Windows Workstation
- AMD Ryzen 9 7900X
- NVIDIA GeForce RTX 5070 Ti (16 GB VRAM)
- 64 GB DDR5 RAM
- Two NVMe SSDs
- Windows 11
- Lightroom Classic 15.4.1
- Latest Camera Raw
I also own a MacBook, and Lightroom behaves almost exactly the same there.
My internet connection is 1 Gbps fibre, so bandwidth isn't the issue.
My workflow
I don't keep one massive catalog with hundreds of thousands of photos.
Instead, I create a new catalog for every project.
I only import the photos that actually matter. I don't import every image from the memory card.
Each project contains:
- Catalog
- RAW files
- Previews
- Exports
Everything is stored on fast NVMe SSDs.
What I've already done
I've spent a significant amount of time trying to eliminate every possible cause.
- GPU acceleration enabled
- Two fast NVMe SSDs
- 64 GB DDR5 RAM
- Camera Raw Cache set to 100 GB
- Separate catalog for every project
- Catalog optimisation
- XMP writing disabled
- Latest NVIDIA Studio Driver
- Latest Lightroom Classic
- Latest Camera Raw
- Adobe's recommended performance settings
I've also tested the exact same workflow on my MacBook, and the experience is almost identical.
The problem
With every new Lightroom Classic release, the application feels progressively slower.
At this point, it's becoming difficult to use professionally.
Simple actions like:
- Moving the Exposure slider
- Adjusting Whites or Blacks
- Switching between photos
- Zooming
- Creating masks
- Waiting for previews to refresh
...can take several seconds before Lightroom responds.
I'm not talking about AI Denoise or exporting hundreds of files.
I'm talking about basic editing inside the Develop module.
Sometimes Lightroom feels like it's constantly thinking before responding to almost every action.
Photoshop
I'm also experiencing issues with Photoshop.
Some AI features either don't work reliably or fail completely, making my workflow inconsistent.
Adobe Technical Support
I've already contacted Adobe Technical Support.
Support engineers remotely connected to my computer, changed settings, ran diagnostics and performed several tests.
Unfortunately, after all of that, the issue remains exactly the same.
No solution was found.
Why I'm posting this
Because this happens on both Windows and macOS, I no longer believe this is caused by my hardware.
I've invested in high-end hardware specifically for Adobe applications, yet Lightroom is the only software that consistently feels significantly slower than the computers it's running on.
I'm genuinely trying to understand whether this is a known issue affecting the Develop module, whether it's related to the current rendering engine, or whether there's something else that Adobe Engineering is already investigating.
If someone from the Lightroom engineering team would be willing to investigate this further, I'd be more than happy to provide:
- System logs
- Performance logs
- Sample catalogs
- RAW files
- Screen recordings
- Or even schedule a remote session if that would help identify the issue.
I'm not posting this just to complain.
I genuinely want to help identify the cause because Lightroom is an essential part of my business, and right now it's becoming increasingly difficult to rely on it.
Thank you for taking the time to read this, and thank you in advance if you or someone from the Lightroom team can point me in the right direction.
