Can you do a test of the new noise reduction in LrC and comment on what CPU/RAM seems best suited to take advantage of it?
Thanks!
I have a 2021 MacBook Pro, M1max, 64GB.
After restart, I have open Apple Mail, Safari, Notes and Messages --> 11 GB memory occupied
After starting LR Classic, in develop mode --> 29 GB
Note: ~15 GB of this is consumed by opening the develop mode for the 100MP GFX100 RAF.
DeNoise of a 100 MPixel Fuji GFX 100S RAF:
- Preview ready --> 35 GB
- Executing the DeNoise --> 25-33 GB occupied.
==> All in all, LR Classic is adding approx. 24 GB, of this "only" 6 GB for DeNoise.
I don't know, how much of the 18+6 GB is preview cache. I think, the majority.
I am happy to have done the 64GB investment ... even before this new LR DeNoise AI I had regularly 40+ GB occupied:
- I have Word, Excel, PPT, Teams, Safari open all the time. This plus LR+PS results in the 40+ GB.
- I think, the system is grabbing what is available, and does not free memory of temporarily unused apps.
- But with stitching in PS (8 GFX 100 files), I reach 50-60 GB.
My advice: If money allows it, go for 64 GB.
It helps (maybe only a bit), but future AI updates will continue to increase memory consumption.
And even more, if Adobe implements the AI Denoising without DNG. This will need memory, to store the intermediate non-destructive steps.
Edit:
LR: Timing on 100 MP GFX 100S RAF: 4 sec until preview, 47 sec for denoise.
LR: Same for 26 MP X-H2S RAF: 2 sec / 15 sec.
Topaz DeNoise, 100 MP RAF: 14 sec until preview, 14 sec to process and store (16 bit TIF)
Topaz DeNoise, 26 MP RAF: 9 sec until preview, 9 sec to process and store.
