i don't think this method should be used unless mods aren't working for some reason.
Mods seriously correct the huge lag issues the NA version of mabinogi has.
- The netcode in mabinogi is designed for korea where everyone gets about 10 ping max. Devcat never bypassed nagle's algorithm because its not necessary in korea, but its a huge problem in the NA version where the large majority of players get medium~high ping. Abyss fixes this.
- The font in the NA version of mabinogi is terrible and makes your game halt opening chat windows or any menus. Abyss fixes this by changing the font to a much better one.
- Mabinogi was designed in an era where single-core computers were a thing, and by default multithreading isn't enabled. This seriously lowers FPS and Abyss fixes it.
