Command lines

• Multiple command lines should be separated by a space.

Command	Notes
--waitforpreload	This causes the game to not finish the initial loading screen until it has fully loaded all of the stuff that would otherwise be background-loaded during the first moments of play.
--noasync --nopreload	Completely disable the asynchronous loading changes introduced in Version 2.3.0.
--require-launch	Require that the user press the launch button in the patcher before entering game.
--nopatch	Do not attempt to patch.
--fail	Fail horribly.
--garbage-generation <generations> -gc <generations>	The number of generations to keep around when running garbage collection. While this feature fixes out of memory (EOUTOFMEMORY or Unable to Map File) crashes it significantly increases loading time between zones. Valid values are 1 or 2. e.g. -gc 2
--nosound -ns	Disables the creation of the audio device. Helps with sound related crashes.
--softwareaudio -swa	Forces use of generic software audio device. Fixes a bug with Creative sound cards causing game crashes.
--login-port <port number> -lp <port number>	The login server port. e.g. -lp 3724
--patching-server <server> -p <server>	The patching server that should be patched from. e.g. pathofexile.com:3724
--patching-auth -pa	Override basic auth used for for patching content.
--prev-proc-id <process id>	Before running wait for this process id to exit.
--use-defaults -ud	Will always use default settings set in the settings.cpp
--adapter:<adapter number>	Selects a video adapter. Do not use this command, but instead use your graphics driver menu, or set this by right-clicking on the Path of Exile shortcut and choosing to run the game with the dedicated graphics card. e.g. --adapter:0 selects the first adapter

Version history

Version	Changes
2.4.0	"--experimental-frame-optimizations" option has been removed. Its functions has been added to the core game.
2.3.3	This patch introduces an opt-in beta test for the new multithreaded engine features that should significantly improve game performance for most users. Frame rate increases are most significant when there are a lot of entities in the scene. This means situations with large amounts of combat should have much more stable frame rates. Do not expect significant increases in frame rate in non-combat situations. To enable this, you need to add "--experimental-frame-optimizations" to the Path of Exile command line.
2.3.0f	Added --noasync command-line parameter to completely disable the asynchronous loading changes introduced in Version 2.3.0. The --nopreload mode now works the same way as --noasync. The asynchronous loading is turned off but data is preloaded correctly (resulting in long loading screens, but no stuttering). You should remove --nopreload and add --noasync to your shortcut for future compatibility.
2.3.0e	Added --waitforpreload.
