Snd noextraupdate

Name: snd_noextraupdate
Default value: "0"
Flags:

0 = Makes Quake update its sound buffers more often to avoid choppy sound when your fps is really low (20 or worse)
1 = Don't use extra sound updates. Gives a slight fps boost, but may lead to choppy sound on low-end machines

Note: Toggles the correct value display in host_speeds. Usually messes up sound playback when in effect (haven't verified) ~ Moodles
