Quick answer: Godot 4 high-level multiplayer producing 100KB bursts when many projectiles spawn? RPC spawn message bloated; switch to MultiplayerSpawner for compact spawn.
Player fires a 50-projectile shotgun; client sees lag.
Use MultiplayerSpawner
Compact spawn message; smaller than per-projectile RPC.
Or spawn one container projectile
One networked entity; client expands locally to 50 visuals. Bandwidth halved.
Throttle volley spawns
Spread spawns across 5 frames; bandwidth per packet drops.
“Per-projectile spawns scale poorly. Aggregate the spawns.”
If your game has volley-fire mechanics, the spawn architecture is a network architecture decision. Plan it.
