Arma 2: Undocumented Command Line Switches
If you are just looking for the normal ArmA2 startup switches, please go here Arma2: Startup Parameters
Note: This is a work in progress of all the allowed switches, these have not been tested. I will try to document them as I figure out what they do. Many of these are already known and the information will be redundant. The list was generated by hand from info in the binary and I left all switches for completeness.
- 1 Configuration & Performance
- 2 Graphics
- 3 Sound
- 4 Network & Multiplayer
- 5 Development

Unknown, but likely gets rid of ESRB warning when clicking Multiplayer.
Unknown, may set aside MP slots for local connections only.
Self explanatory, but usage unknown.
Microsoft Gamertag. I doubt this does anything, it is a remnant of the Xenon code.
Self explanatory but usage unknown. An autotest is used by developers to test the functionality of a build in an automated fashion.
Self explanatory. Errors appear in black box at top of screen.
Use shader model 2.
Use shader model 3.

Guess: Same as above but loads addons?
Disables PBOPrefix handling, game will only load .pbo files and not the unpacked directories.
Guess: Disables check for newer patch on MP server select screen, disabling nag.
This may have something to do with the shell association introduced in 1.05.
