I've been working on a large combat system and I'm running into serious performance issues when handling client-side inputs that trigger server-side validation. My current setup feels really laggy, especially when multiple players are active. I'm trying to figure out if I should be using RemoteEvents more often, or if there's a better architectural pattern for managing state changes. Has anyone successfully implemented a robust system for handling high-frequency data transfer without causing network bottlenecks? Any advice on throttling or predictive client-side logic would be greatly appreciated.

You should absolutely look into a client prediction model combined with server reconciliation. This is the industry standard for fast-paced combat systems. The client predicts the outcome instantly, and the server corrects it when the authoritative state arrives. It minimizes perceived lag dramatically.

Have you considered using a dedicated networking library instead of relying solely on basic RemoteEvents? Sometimes the overhead of Roblox's built-in events for high frequency data is the bottleneck. Look into optimized packet handling or message queuing systems.

Short. Throttle everything.

I found that batching inputs is key. Instead of firing a RemoteEvent for every single movement tick, collect the inputs locally for a short window (say, 50ms) and send them as a structured array to the server. This drastically reduces the event spam and helps manage network overhead.

That's a solid point about batching. But how do you manage the timing? If the client predicts based on a 50ms batch, and the server validates against the actual state, won't the correction window become too large and feel jarring to the player?

You need to implement interpolation on the client side for received state updates. When the server sends a correction, don't snap the character instantly. Instead, smoothly transition the character's position and rotation over a short duration (e.g., 100ms) towards the corrected position. This makes the corrections feel natural.

Think about the data structure itself. Are you sending raw coordinates every time? Use relative changes or vector deltas whenever possible. Sending 'move 5 units forward' is much lighter than sending 'position (X+5, Y, Z)' repeatedly.

I agree with the interpolation suggestion. It's crucial. Also, for combat, consider using a 'request' pattern. The client requests an action, and the server responds with a 'confirmation' or 'failure' state, rather than just processing the event immediately.

What about rate limiting on the server side? Even if the client sends a burst of data, the server should enforce a minimum cooldown or maximum frequency for critical actions (like ability usage) to prevent abuse and stabilize performance.

A combination of all of the above is necessary. Batching inputs, interpolating client-side, and implementing server-side rate limiting provides the most robust architecture. Start with throttling the input stream, then move to prediction.
