I have updated the specific thread about the PFDs’ and glass cockpits’ refresh rate optimization (link: Small JS config file mod to gain 10/15+ FPS in airliners and glass cockpit planes) with an archive containing both options (with several refresh variants) ready to be used in the Community folder: the “original” one with the divider and the new brilliant fixed Hz solution provided by @CptLucky8
Many refresh rate options are included in the ZIP. Please check it out if you want to try the new method, which is much better in my opinion!
Let me know what you think!
