In-Game Settings (Continued)
Disable All Sounds - When selected will disable all sounds in the game. I recommend against selecting this unless you're absolutely desperate for a performance boost and/or you have horrendous sound problems. Gameplay is all but impossible with no sound.
Master Volume - This controls the overall volume of the game, including sound effects, music and voices. Set to taste, has no effect on performance.
Music - When selected, plays background music during the in-game menus. Deselecting it gives a slight performance boost for those with 512MB of RAM or less.
Music Volume - This controls the volume of the music only (if the Music option is selected). Set to taste, has no effect on performance.
Quality - You can choose 11Khz, 22Khz or 44Khz sampling rates for the sound in the game. The lower the setting, the better your overall performance and fps, but the lower the sound quality. In particular, if you have 256MB of RAM or less, choose 22Khz or lower. Further, some people will have sound loss/glitches with higher sample rates, so select 11Khz or 22Khz to resolve these (See Troubleshooting section). Generally I recommend 22Khz for most people as it's a good balance between quality and trouble-free performance.
Sound Detail - Has Low, Medium and High settings. The higher the setting, the more sounds get played but the lower your overall performance. As you lower the sound detail, only the more important sounds will be played (such as your gun firing, vehicles nearby, etc.). I recommend at least Medium sound detail otherwise you will be severely disadvantaged in gameplay (e.g. not hearing approaching players/vehicles). Try lowering Quality and Channels first before lowering this setting if you need a performance boost.
To access the following options, press the small arrow on the bottom right corner of the Sound box.
Hardware Acceleration - When selected, this option will use your sound card (if supported) to play sounds. This should theoretically result in a performance improvement, however some sound cards may experience sound glitches with this option on, such as I did with my Audigy (See the Troubleshooting section), and you may also see a performance decrease. Deselect it in this case and you may even have better performance for it.
Channels - Determines how many channels are used for sounds, ranging from 16 to 64. The more channels, the more separate sounds can be played at once. However, the more channels, the lower your performance and the greater the chance of audio glitches. If you have Hardware Acceleration selected, you may not get a choice of channels as the game will automatically use all available channels on your card. I recommend if you have the choice, to set number of channels to 32 (or even 16) for best sound quality/performance balance, particularly if experiencing audio glitches.
English Dialog - When selected, plays back all your team's voices (including your own) in English, and enemy voices in their native tongues. When deselected, you and your team will shout out orders in the native tongue of the team. E.g. if on Axis, your radio commands will be in German (but with English text displayed).
Click the Save button to save your sound options. Note that some sound option changes will not come into effect until the next time you load up BF1942.
While I won't go through all the options available here, the performance-related options are covered below.
Number of Bots - This setting determines how many computer-controlled characters ('bots') will be on your team and the enemy team. The higher the percentage, the greater the number of these bots. The more bots, the more characters may be represented on the screen - hence putting more load on your graphics card, and the more Artificial Intelligence (AI - see below) the computer has to manage, which affects your overall performance and fps.
CPU Time Given to AI - This setting determines how much effort the CPU puts into managing bot AI. The higher the setting, the better the AI, but the lower your performance. When combined with the number of bots (see above), this setting will noticeably impact on your fps in single player. If you have a 1Ghz or lower CPU, set this to the lowest available, particularly if you have a large number of bots. Faster CPUs can raise this setting, but only very fast systems should attempt large bot numbers with high CPU time for AI.
