Version history

Version	Changes
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.
