Noise Reduction Preview not working unless zoomed
I'm new to using the Noise Reduction Tool in C1. I'm on the latest version running on an M1 MacBook Pro. Why does C1 only preview noise reduction adjustments when zoomed in? Is there a way to see the noise reduction applied to the zoomed out image?

No, it's always been like that.

Any particular reason why? Is the only way to see the final image with NR applied, but exporting the image?

I think the reason is that in the preview, assuming you have a fairly large image - larger in pixels than your screen - it is inevitable that the preview has to squish pixels together to give you an image to look at. For instance if your image file is 6000x4000 (24 MP) and your preview is 2400x1600, the 24,000,000 pixels in your image are represented by only 3,840,000 pixels in the preview, so that each pixel on your screen has to represent some kind of combination of about 6 pixels from the image file. Inevitably any representation of the noise reduction would only be approximate and the only real way to tell how much you need is to view it at 100% (so the 1 pixel in the image is represented by 1 pixel on screen).
Also it is certainly true that the output is the real test. You might have an image that is too noisy to print full size without some work, but if you are producing output for Instagram it may look perfectly OK, because of how it will be viewed.
You could look into recipe proofing to see how you could simulate what your output will be like.

This is common elsewhere too. For example in DXO Photolab the DP noise reduction can only be seen in a preview window for a zoomed-in view of only part of the image.
