I find the "P" key (red option -- View > Focus Details > Fine Details) -- I'm viewing on a 4k screen, but not at 1:1 pixel ratio. It's easier to compare two similar images if you open FastRaw twice, open both in the same folder of images, then Alt-Tab between the two instances of FastRaw, one instance open to image A and the other instance opened on image B. Use the "p" command to get to the red screen, then Alt-Tab between the two. Do it again with the regular image. Do that for two images where one is obviously out-of-focus and one is in-focus. You'll pretty quickly see how to use the red "p" view to see what is in better focus. Especially where you see bright red lines of contrast on the object of interest.
