Create illusion of "between tick effect"

[Apeirogon]

As it say, how, and is it possible, create ILLUSION, not actual simulation, that gzdoom can simulate actions on screen more ofthen than 1/35 seconds?

Example, I want to make true realistic minigun, which can shoot ten hungred milion thousend billions projectile in minute.
I well aware that I can spawn/spam as much projectile as I want in a single tick, in decorate and zscript and acs.
But from player perspective, its visible that with such rate of fire, more than one bullet in tick, minugun look like some weird kind of shootgun, which sounds like "PEW PEW PEW" instead of "BOOM...SHUC-SHUC".
So I want to make illusion, rendering illusion I think, that this minigun constantly shoot bullets, without 1/35 seconds pause.

Try offsetting the projectiles' positions -- e.g. if you're shooting 5 projectiles per tic, spawn projectiles 2 through 5 further away from the player. That'll make it look like a stream of projectiles rather than a series of shotgun bursts.

Mix the shot sound so you've got two going off 1/70th of a second apart, then play that every tic instead of the regular shot.

This is not about sound, but for visual part of weapon.

Dont help in case if I need something like laser aim, like in project brutality, or which work like "constantly shoot a_bulletattack() and make it puff look like laser dot".

Be more specific with your help requests then. You didn't mention anything about laser sight effects, and if you're looking for a "one size fits all" solution, there isn't one.
