No, it's only enabled on vgmplay in mainline. You can edit one line in src/devices/qsound.h if you want to enable it for all drivers with QSound - see here: https://github.com/mamedev/mame/commit/3f67473bb42a6e8c5a47d73abe1ddbfb8118ee1c#r28107223

The performance varies depending on your CPU - memory controllers are king. You can get over 100% in CPS2 with QSound DSP on a Haswell-E or a Xeon E5v2, but a regular i7 without the amp'd memory controllers is likely to dip to around 70% or so.
