This is a picture from over in the SH4 side of things here, but you will most likely have to further mess with the "Properties" settings of the SH3.exe file, and "Change high DPI settings", at the least. You might also have to set the "Disable full screen optimizations". I have one computer where I have had to use that "Use this setting to fix scaling problems..." and then set the "Use the DPI that's set..." and put it to "When I load this program", or whatever the "program" choice is. See what happens. A question though: What folder and path do you have the game installed?
