enabling hinting helps with the fuzziness. Have to run REGEDIT2 to modify it. From the readme:
All configuration data is stored in the OS/2 registry and can be edited using the OS/2 Registry Editor (regedit2.exe). The reason for using the registry instead of e.g. OS2.INI is the much higher flexibility of the registry compared to the limited OS2.INI format. The configuration data is stored below the key
