Use reshade 3 fps font in reshade 4

I much prefer the smoother font that reshade 3 uses for the fps and frametime counter than what reshade 4 currently uses. How could I modify reshade 4 to use the same font as reshade 3?

You can change the font, but it will affect the whole UI, not just the FPS counter. Go into the Settings tab and scroll down to the "User Interface" section. There is a "Font" option there, which accepts paths to TTF files. The font used in ReShade 3 was "C:\Windows\Fonts\consolab.ttf".
