Question

AI Noise Reduction in Lightroom Classic is very slow

I wonder if there's a simple fix for this.

The new Noise Removal AI in Adobe Lightroom is unusually slow on the NUC 12 Pro i5. De-noising a single Canon RAW CR3 photo takes 6-8 minutes.

The Topaz noise reduction AI software takes just 9-10 seconds to denoise and export the same photo on the NUC. (I greatly prefer the results from Lightroom Classic Noise reduction AI - so would love to get this resolved.)

Don't know if it's relevant, but I'm running OpenCL because Davinci Resolve 18.5 won't run without it. The NUC has 64GB RAM and photos are on a fast Samsung 980 SSD.

I'm using the NUC internal Iris Xe graphics.

Would be grateful for your thoughts.

George

Your figure of 6-8 minutes is not unusual for a computer using an internal GPU of above type.

 

The Iris Xe is has slightly better performance than an NVIDIA GT 1030. Therefore, I've provided a link below to a thread (closed) where GT1030 users describe timing similar to your Iris Xe.

Thank you, Ian. I reckon I'll keep using manual NR applied to batches. It's mystifying to me (non-tech-enabled) why Topaz can correct noise and convert and save a 100+MB file 60 times faster. Go figure. Perhaps different app design delivering varied results.

One possible explanation is that AI Denoise is only a few months old, while Topaz has had a long head start to optimize the performance of their code. We’re all hoping there are further performance optimizations to come for AI Denoise. The blog article Adobe posted at release said they are exploring a lot of ideas for improving AI Denoise.
