While on Macs the Mac/AV latency may be good enough for realtime playing of
virtual instruments, on Windows:
a) there's no such thing as a generic AV driver/card, so there's no "common"
latency adjustment trick either,
b) most "standard" MME cards don't deliver low enough latencies to even
think about realtime playback.

The only solution is to get a card coming with proper ASIO drivers (well,
lately I heard quite some good reports about low latencies for some WDM
drivers, the Delta cards have very good ones I think).
To lower that latency you gotta check your cards driver/ASIO setup utility.
Anything below 10ms should give you a feeling being as good as many
standalone modules being played through MIDI. The appropriate buffer setting
at 44.1kHz should be something between 300 and 500 samples (512 samples @
44.1kHz = 12ms latency).
I don't know about the GINA, but it should offer buffersizes that low.
Usually the lowest available buffersize however raises the CPU burden a bit,
so I would try if the second to lowest setting is still good enough
(personally I am pretty happy with the 6ms I'm getting out of my current
card, a TerraTec MT88).
