FractionalGui
adds more options for gui scale
About this Mod
FractionalGui
1.21.6 and higher: Mojang changed the internal representation of gui scale from a double to an integer which makes the method used by FractionalGui not work anymore. There won't be further updates until I find a solution or archive the mod.
FractionalGui is a simple mod that adds more intermediary options for GUI scale.
WARNING: this mod is somewhat experimental and kinda wonky, weird rendering is to be expected
There are currently no plans to add antialising to the UI; but feel free to open a PR if you think you could make such a thing work!
