UIMPI

Performance Limiter for BeamMP

A lightweight and optimized performance rating system for BeamMP servers. Automatically calculates vehicle performance ratings and enforces server limits in real-time.

Features

Performance Rating

• Calculates a Performance Index (PI) for every vehicle in real-time
• Rating factors: engine power, torque, weight, drivetrain type (RWD/FWD/AWD), tire grip, and braking force
• Four rating classes: D / C / B / A
• Dual-motor EV support

Enforcement

• Vehicles exceeding the server limit are automatically frozen
• A 2-point display offset is applied to the visible limit — players see a slightly lower number than the actual enforcement threshold, compensating for mid-drive fluctuations
• Frozen vehicles receive a clear in-game banner explaining the reason and how to fix it

In-Game UI App

• Displays live vehicle stats: HP, weight, torque, brakes, grip, drivetrain, RPM, gearbox, induction type
• Color-coded stat indicators showing each value's impact on the rating:
  • 🔴 Red — Max Impact: increasing this value will no longer affect the rating
  • 🟠 Orange — Affects Rating: changing this value will raise or lower the rating
  • 🟢 Green — Below Minimum Impact: decreasing this value will no longer affect the rating
• Rating badge pulses red with a ⚠ warning when the vehicle is over the limit
• Toggle stats panel by clicking the rating badge

Vote System (optional)

• Players vote to change the server performance limit
• Configurable options, duration, and admin controls
• Real-time vote results with progress bars in the UI

Multilingual Support

• Language is detected automatically from the player's BeamNG settings
