http://windows10_dpi_blurry_fix.xpexplorer.com/ After more playing I found this font fix that worked in RS1 makes RS2 and beyond a lot nicer (IMO) to use. Instead of scaling the fonts within Legacy apps it will leave them as they were (small and sharp) this improves things a lot for how far away I sit from my screen, Give it a go and if you don't agree (after a reboot) then you can easily run it again and Pick use Win 10 Scaling.
Seems to work well, but then I'm on 1920x1080 on a 23 inch monitor, so the real test would be on 2 or 4k screens or 1080 res on smaller screens. The following seems to explain a lot more than just dpi scaling: Hehe, that's why we have that gawdawful Win10 interface at all. But this is a great app to have, it allows for some customization as the various resolutions don't always work very will on different sized screens. Good find
