Use Compact F3 Plus on Multiplayer Servers

Client-Side Mod Advantage

Compact F3 Plus runs entirely on your computer and requires no server-side installation. This means you can use it on any multiplayer server—vanilla, modded, or otherwise—without asking administrators for permission or waiting for updates.

Checking Server Performance

The overlay helps you diagnose whether lag comes from your computer or the server:

1. Open the debug display and note your FPS

2. If FPS is high but gameplay feels slow, the server is struggling

3. If FPS is low, your client needs optimization

This distinction is crucial for troubleshooting: server lag requires admin intervention, while client lag requires your own settings adjustments.

Playing Without Disruption

Because the mod is client-only, other players cannot see your debug overlay, and your presence doesn't affect server performance. You can monitor your connection quality and frame rate freely during multiplayer sessions without impacting anyone else's experience. This makes it ideal for competitive play or shared servers where you need real-time performance data.
