# Features

A lot of bugs and exploits from MOH:AA were fixed in OpenMoHAA (BOF exploit, grenade crash bug, command overflow...).

## Summary

- SDL2 backend
- OpenAL sound support (better sound quality)
- Full 64-bit support
- Cross-platform support
- Multiuser support on OS (On Windows, user game data is stored in "%APPDATA%\openmohaa")
- Many bug fixes and additions from ioquake3
- Automatic scaling of UI elements on high resolutions like 4K

Overall, better compatibility on modern systems and bugfixes.

## Additions

### Client-side and server-side

- Demo recording
- Features from ioquake3
- Features from MOH: Spearhead 2.15 and MOH: Breakthrough 2.40
- IPv6 support (from ioquake3)

### Client-side

- OpenAL and SDL are used
- Smoother animations
- Stufftext protection: commands that the server want clients to execute are now filtered

### Server-side

- Bots
- IP ban (from ioquake3)
- More script commands for mods
- Non-PVS optimization
- Packet flood protection
- Ability to enable/disable the text chat and the voice message chat and set a delay between chat/instant messages

#### Non-PVS optimization

For each client, the server optimizes by only sending them information about other players that they can see. Clients won't see other players they can't see.

Enable this feature with `set sv_netoptimize 2`.
