Noise reduction in RAW slow with GPU on

Removing noise in raw works very much faster when I switch off the GPU.

GPU off max. 30 sec. GPU on, many minutes

Canon RAW cr2 and cr3 Canon 5D DS r and R6.

Can't understand, for Adobe advises to switch it on, so it would be faster.

Maby a bug, I don't know.

My computer:

Adobe Photoshop-versie: 25.4.0 20231220.m.2439 ceb99ef x64

GPUName: NVIDIA GeForce GTX 1660

Memory for Photoshop: 103684 MB

Win 11 pro. NL

13th Gen Intel(R) Core(TM) i7-13700F

Windows

Something doesn't make sense here. You can't turn the GPU off in ACR - it now needs GPU support to run at all - and ACR is where Denoise is executed.

You need to explain in detail what you're doing.

It is the new function with AI in raw for denoise.

Are you specifically using the new "Denoise" function? Or is this the old and traditional noise reduction? Those two are very different.

That Denoise will take a minute or two on a GTX 1660 is expected. Denoise really requires a newer RTX-series GPU, which has Tensor cores optimized for AI-based operations like Denoise. On an RTX, it typically takes 10-15 seconds.

NVIDIA GeForce GTX 1660 6GB with the latest drivers.

No, its the only part of Photoshop were this occurs.

All other functions in Photoshop works fast.

Thank you Leo, for letting us know that it is running slower with the GPU turned on. What graphics processor card are you using? Is that the only thing in Photoshop that slows down wit it turned on?
