FYI, noise reduction is only visible on output. So if you are looking for fine comparison of fine art images considering DeepPrime, the only option is to export and use an external viewer. More detailed notes on compare here.
The downside for having DP and/or DP XD on the full size realtime image is that it has to calculate it constantly, meaning that an update of the live image takes a much longer, depending on your hardware.
For instance, if applying DP XP takes a minute on your machine while exporting, updating the live view will also take a minute. And on older hardware or without dedicated GPU it can even take multiple minutes. Processing DP XD on my machine without enabling GPU acceleration takes about 5 minutes for instance.
Is that really what you want? Or do you mean comparing images after export? That one I can relate to but I understand your question/suggestion as the first one (applying it on the realtime view).
Hi, that’s correct and will be similar to the Topaz photo AI function.
But I can say that with my MB Air M1 it doesn’t take sooo long time. And if you have had the preview choosing one model and jump forward or backward within the model settings it’s not necessary to save the output file to compare till you have made your choice of the setting that fits.
I think they keep it in RAM or virtual RAM…this only having a idea behind the technical curtain.
On my AMD RX480 dedicated GPU, exporting a jpg with XD takes around 25-30s. But if I use my much more modern Ryzen 7 laptop, which CPU is more powerful but the GPU is not, it takes around 70s.
I don’t know if DxO is saving the snapshots from the advanced history in memory. That would use a lot of memory and when you’re out of free memory you would start to swap, which is slow compared to RAM.
Don’t get me wrong, having a realtime view of de denoising would sure be nice, but not at any cost.
