    • I have a low-end / slow / old / computer, how should I configure Project64?

    • I have a fast PC, how should I configure Project64?

      First let me define "fast PC" - recommended spec or higher (see User Manual) .
      I recommend you leave most things at defaults, except

      1. you could disable ABL to possibly smooth some games
      2. you could try changing CF to 1 as it smooths some games

      But these settings do not always work so try at your own risk and be ready to put them back where it causes problems!

      Hgh levels of filtering can be used in the video plugin.
