Hi, I am experiencing some gameplay sound lag. When I shoot the sound comes half a second later. It is very annoying.
Are there any setup to fix this in Dosbox? I know GOG uses dosbox to power this game

I had an issue with FMV lag, these DOSBOX settings helped and may also help your issue.

[mixer]
nosound=false
rate=44100
blocksize=1024
prebuffer=50

It helped be too, thanks mate.
Awesome game! :)

I second this. I had the sound effects delay that the original poster mentions, so I tried the above settings; works a treat now! Cheers, rjspring :)

Yup if the sound buffering cache is too big the sound starts to lag, I've noticed several Dosbox games on gog.com which are configured with too high buffer values.

To be honest, someone (who's smarter than me) should do a topic/guide about this issue with DOSBox; giving suggested settings for some DOSBox games that are known to have problems with their default settings. I had the SFX delay with Duke Nukem 3D - which comes with a DOSBox - also.

Slightly off topic, but still to do with DOSBox: I never understand what to do with 'Cycles'. For example: in Crusader: No Remorse's cfg file, it is set to 'Max' by default. The comments on the file say you can set a value. Thing is, I don't have a clue what number to choose. Apparently this value can affect the level of lag; - whether that means audio lag or input lag, or what - isn't crystal-clear, though.

Though there are plenty people who fully understand DOSBox, there also seem to be a lot of people (like me) who don't fully understand the intricacies and complications of every setting.
