NK> BENCHMARK%: V: 20.7046% VO:  3.1270% A:  1.3208% Sys: 74.8477% = 100.0000%

NK> BENCHMARK%: V: 20.4299% VO:  3.0761% A:  1.3063% Sys: 75.1877% = 100.0000%

NK> Could you explain me: what's difference between first string and second?
NK> Why Systime always 100%? What means 's' suffix in the first string.
it's total percentage and always 100% of course, systime includes also
idle calls of course so if other percentages go down, systime will go
up (at least if ya play with sound). s suffic imo means seconds.
NK> Why VO is changed too? Where AO time? Does 'V' include 'VO'?
VO time is time dneeded by vo plugin to display image (there can also
be extra systime spend for it not shown in there) and V doesn't
include VO, think AO isn't calculated cause audio device cpu time is
very minimal.

NK> Thanks!

NK> Best regards! Nick
