3D game emulation is still in the infancy stages. The sound is crappy (usually) and the game runs a little slow (almost always), but if your computer is beefy enough you should play alright. For example, Battle Arena Toshinden runs a little slow, and sometimes the characters stutter when they talk, but it doesn't sound horrible. To mirror this, my Plasma Sword looks great and plays as fast as I expect it to on an arcade cabinet, but the sound skips, echos, stutters, and blares. All we can really do is wait for emulation to become more sophisticated.
