Generally speaking it feels better and makes for better gameplay, even if that gameplay is unrealistic. Most games have projectile weapons that have some lead time so there isn't much of a performance reason. HN users tend to think deeper/more complex simulation is directly correlated to better gameplay (see the sword conversation above), but one of the interesting things about games is abstraction. That said more simulation focused games with larger maps (some Battlefield games, ARMA) have bullets with travel velocities and bullet drop.
