Setting	Default	Description	Recommended
Song caching	On	Enabling this will save compiled songs for later play. This is useful for not reconverting a chart over and over again. Note that this will take up space depending on how long the charts are.	Ambiguous. This option was made as a way to avoid waiting for audio to be encoded, but encoding has gotten faster in recent updates.
Verbose logging	Off	Log specifics of what's happening during chart conversion.	Ambiguous. Useful for finding where a specific error is. All verbose logging will always get written to launcher.txt.
Preserve log	Off	Require a key press to exit out the launcher after chart conversion.
Disable Vsync	Off	Play the game with an unlimited frame rate, if not capped by Max FPS option.
No startup message	Off	Disables the welcome/about message before asking for a chart file to play.
Exit on song end	Off	Exit the game once the song ends. DUUURHHHHH
Keyboard mode	Off	Enables playing with the keyboard or manually choosing a controller. Requires at least one button to be pressed on any controller to ensure which one is allowed to play.	Yes: if you switch controller ports often. No: if this is the only controller-based game you play lol, or don't have a guitar and play keyboard only.
Debug menu	Off	Enables debug menu with more options and functions.	For fun, or further investigation of bugs.
No intro	Off	Disables highway and HUD intro animation and instantly displays them.
No particles	Off	Toggles particles. Modes: All: all particles displayed Minimal: no note hit spark and star particles Disabled: turn off all particles including flames and lightning
No fail	Off	Disables the Rock Meter.	No. or yes with caveats
Easy expert	Off	Cheat from default GH3.
Precision mode	Off	Cheat from default GH3.
Background video	Off	Enables background videos. (requires Bink video files)
Hide hit gems	Off	Makes notes disappear as soon as they're hit, like in every game besides 3 and Aerosmith.
Early sustain activation	Off	If a long note is hit too early, the game waits until the note reaches the nowbar to start scoring. This option can make it so sustain score is awarded immediately even when hitting a long note early.

Misc

Setting	Default	Description	Recommended
Max framerate	0	Set max FPS, if not capped by Vsync. If set to 0, the frame rate limit will not take effect. Warning: Some frame rate values will make the game look choppy depending on the refresh rate your monitor supports, or depending on your GPU.	Varies.
Audio quality	128	Change the bitrate used for converting songs in kilobytes/sec. This will only take effect for the next songs converted. If song caching is turned on, the cached songs will keep the bitrate setting they were converted with. Note: This will also result in larger compiled audio files, which effects your song cache as well.	Optimal setting where quality loss isn't noticeable while taking the least space.
Ready time (no intro)	400	Set the amount of time before the song starts (in milliseconds) when 'No intro' is turned on.
Song Text Format	%a - %t	Change the format of currentsong.txt. Can be useful for streaming.
