Microsoft Copilot+ PC Lightroom CC AI Denoise

Hi, The same for me surface pro 11 X elite 21/05/25 DENOISE AI on Lightroom between 8 min and 11 min IT S TOO LONG !! with dxo pure raw 5 it s around 2 an 3 min 

It s look like ADOBE priority, no focus on ARM after almost 1 year, 

Surface Laptop 7, 13.8-inch.

Lightroom ARM works great, except Denoise is extremely slow. According to mask manager the GPU is pretty much at 100% the entire time. Possible it's a driver issue? Qualcomm is doing a lot of work to optimize their graphics drivers, and per Tom Warren, there's a big driver update in the works.

Yesterday I also got an Snapdragon X Elite notebook. Performance is great, no complains here. But as you said the AI denoising is extremly slow. I checked in the task manager, and it only uses the gpu. I assume it should be using the npu, but Adobe didn't optimize Lightroom enough yet for it to be using the npu.

Thats my guess. 

To be honest, thats a pretty whack move from Adobe, to not support it when those notebooks are already released. I get it the notebooks are new and I also could have waited a few weeks or months. But since Lightroom is running on those arm machines out of the box and do not need to be translated from prism, you should expect it to work.
