Tweaking Tips – ArmA: Armed Assault

Texture Details

Very Low
Low
Normal - for graphics card with 256 MB physical memory
High
Very High - for graphics card with 512 MB physical memory
1.08 Default - this setting is designed to fully utilise graphics card with over 512 MB and any other card with unusual size of installed memory. It sets texture quality at their maximum level and automatically estimates the available memory

Dedicated Server Bandwidth Settings

Bandwidth Settings can be found in the arma.cfg in /My documents/Arma/

Min/Max Bandwith

Lets start with Min and max Bandwidth settings for arma and min errors to send.

The more players hosted the more bandwidth the server requires to keep everything smooth.

Most players normally use 5-13kb when playing in game but will spike up on certain events such as players joining or when downloading content so a standalone dedicated server connected to at least a 10Mbit line is recommended for optimal play.

To determine Min/MaxBandwith server requirements, the examples below can be used as a guideline.

256kb Minbandwith, 512kb MaxBandwith times X number of Players use So 256kb X 20 Players = 5120000

MaxMsgSend

Lower values are suggested for CTF/DM maps and higher values for evo/CTI
Using too large of MaxMsgSend in a CTF causes stutter effects

Recommended values: CTF/DM: 128/192; evo/CTI: 384/512

MaxSizeGuaranteed

Should not need to be changed.

MaxSizeNonguaranteed

Raising this value means players are sent less bandwidth for events such as soldier or vehicle position, e.g a lower value prioritises those events.

MaxBandwidth

Max limit the server can send to players.

⚠

Raising this too high can cause the server to send more data than clients can process which causes instability.

Examples

Suggested Server min/max Bandwidth for dedicated servers

256kb Min/512kb Max × number of players

12 players

24 players

32 players

64 players

MinBandwidth = 3072000;
MaxBandwidth = 6144000;
MinErrorToSend = 0.05;

MinBandwidth = 6144000;
MaxBandwidth = 12288000;
MinErrorToSend = 0.05;

MinBandwidth = 8192000;
MaxBandwidth = 16348000;
MinErrorToSend = 0.008;

MinBandwidth = 16384000;
MaxBandwidth = 32768000;
MinErrorToSend = 0.008;

Example 32-players arma.cfg:

MaxCustomFileSize = 350000;
MaxSizeNonguaranteed = 192;
MaxSizeGuaranteed = 512;
MaxMsgSend = 192;
MinBandwidth = 16384000;
MaxBandwidth = 32768000;
MinErrorToSend = 0.008;
