XIV Docs - Client (ffxiv.exe)

Client (ffxiv.exe)

This is the game client executable.

Note

There are two separate executables for DirectX 11 and DirectX 9. The DX11 version is named ffxiv_dx11.exe. The DX9 version will be removed in a future update.

Arguments #

Note

Unlike other executables, passing arguments encrypted with SqexArg is optional for the client. It’s recommended that you do so if you’re planning to use actual SIDs though.

There a few known arguments that work on the normal game client:

DEV.DataPathType
- Guessing that this controls the asset data type used by the client, this is will always be 1.
DEV.UseSqPack
- Guessing that this tells the client to try to load data from SqPack files instead of from regular, uncompressed files. Seems to always be 1.
DEV.MaxEntitledExpansionID
- This is the max entitled expansion ID that the currently logging in user has access to, you will want to set this from your login response.
DEV.TestSID
- This is the SID you get from your login response.
SYS.Region
- Your login region.
language
- Your login language.
ver
- The (base) game version string.
DEV.GMServerHost
- This is the address of the frontier server to connect to. If empty, this will default to the official Square Enix frontier server.
DEV.LobbyHost0X
- This is the address of the Nth lobby available to the client, these are numbered 0-9. If empty, this will default to the official Square Enix lobbies.
DEV.LobbyPort0X
- This is the port number of the Nth lobby available to the client, these are numbered 0-9. If empty, this will default to the official Square Enix lobbies.

Note

For benchmark versions of the game, there is a whole host of graphical options available as game arguments - but this seems to be missing in the retail version.
