[Affinity Photo Preview vs Original Document (Resolution)]

In the attached photo, the image on the right is the original and the image on the left is exactly as it appears by default once opened in Affinity Photo.  I understand that the program reduces the preview quality in order to make things runs smoother, faster, more efficient overall, etc.  However, I have a decently fast and powerful graphics card and other hardware on my laptop and I prefer to have 100% quality (i.e. full resolution) previews as I'm editing a photo, so I can understand exactly how it will look prior to exporting and/or rendering it.  I thought that this would be a relatively easy thing to find online, but I have been unsuccessful finding a solution.

Thank you!
