Some games like bad company, battlefeild 3 and stalker. I beleive the bullet is an actual individual entity fired like a "rocket". I only think ray tracing is nescesary if the bullet will instantly hit the target. When the entity its self in realistic bullets will just be ticking to see if it hits someone.
