--nologo Disables the animated intro along with the sound.

-noasync
--nopreload Do not preload art assets on startup and disable background loading threads. Completely disable the asynchronous loading changes introduced in version 2.3.0.

--garbage-generation
-gc 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
