Note that there are several variants of it:

• the full-featured version of SVP 4 is only free on Linux and works with VLC and mpv.
• the basic yet free version of SVP 4 which only works on Windows and with programs like MPC-HC much like v3.1.7, but has considerably reduced configuration options compared to both the full-featured version and the old 3.1.7 version.
• the paid full-featured "Pro" version on Windows and Mac is largely identical to the free version of SVP 4 on Linux, though on Windows it also works with MPC-HC as well as VLC and/or mpv.

One thing to keep in mind is that interpolating to refresh rates that are exact multiples of the source framerate will provide a smoother result with fewer artifacts - e.g. 30fps interpolated to 120Hz (4x) is better than 30fps interpolated to 144Hz (4.8x) - this is most easily accomplished with something like like MPC-HC's or madVR's built-in automatic resolution changer which can be used to change your refresh rate depending on a given video frame rate (though you may need to create a custom resolution in order to access certain refresh rates on your display).
