Projectiles and ray tracing

Hello everybody

working on a weapon system for my flying pawn for a mobile project.
it seems that ray tracing is cheaper than using projectiles with physics and i’m looking for performance optmimization.
But i really like all the possibilities that a physical bullet offer,and seems to me also easier to setup.

i need a visualization of the projectile so wouldn’t be the same having a mesh shape following the ray cast trajectory?.
or is there a way to mimic the projectiles options using ray cast saving some performance?.

thanks

someone?
