LapbyLap

LAP BY LAP — Procedural Racing Management & Strategy Sim

Lap by Lap is a highly technical racing management simulation powered by a custom-built, lightweight C++ physics engine (<2GB footprint). Experience a racing game where you don’t just watch the action—you manipulate the world and control the strategy in real time.

Take full control of the management pipeline, or hop seamlessly directly into the cockpit with a 1-button AI takeover system that lets you manage the race while driving.

🧠 The Core Engine & Deep Simulation Systems

Unlike traditional racing games that rely on pre-baked paths and static data, Lap by Lap runs an entirely active simulation backend:

• Zero Pre-Baked Racing Lines: All 24 AI drivers on the grid are dynamic, first-class actors making independent physics decisions every single frame.
• Real-Time Physics Calculations: Drivers actively read the track surface, dynamically adjusting their line and velocity based on track grip, camber, banking slopes, downforce, and tire wear and those same limits apply to you when you take the wheel.
• Active Hazard Avoidance: When track conditions change, drivers adapt. The AI calculates puddle depth in real time, actively altering their racing lines to avoid pooling water and spin-outs.
• Procedural Track Pipeline: Run, test, and compete on fully procedural circuits. The custom engine builds functional, race-ready geometry instantly—including dynamic bridge generation when track paths cross water.

🕹️ Play The Free Demo Now (With Twitch Integration!)

Test your skills on a dedicated showcase map and experience the intense synergy between driving and paddock management.

• Race or Manage: Jump straight into the action behind the wheel, or stay on the pit wall managing complex pit strategies and tire wear.
• Deck-Building Upgrade System: Experience a slice of the card mechanics by selecting powerful upgrades that completely alter your car's capabilities in real time as soon as you pass the line.
• Streamer-Ready Twitch Integration: Fully integrated with Twitch chat! Connect your channel and let your viewers directly vote on and choose your card upgrades in real time, turning your chat into your crew chief or your biggest obstacle.

🏁 Upcoming Paid Game Features

The full version of Lap by Lap expands this simulation framework into an endless strategy experience, coming soon to Steam!

• Procedural Track Pipeline: Run, test, and compete on fully procedural circuits. The custom engine builds functional, race-ready geometry instantly—including dynamic bridge generation when track paths cross water.
• Full Roguelike Seasons: Draft and build a permanent deck of tactical upgrades, team components, and driver perks to survive unpredictable, high-stakes racing seasons.
• The Strategy Matrix: 1,000+ Nodes, Infinite Builds
  Take control of a massive progression system featuring a research tree of over 1,000 individual nodes. Customize your team's Power, Corner Grip, Braking, Tyre Life, Acceleration, Reliability, Efficiency, Wet Grip, Pit Efficiency and Race craft  perks to unlock powerful, specialized Race Deck cards.
  • Seasonal Cap: You can only unlock a maximum of 330 nodes over the course of a full season, meaning no two paddock builds will ever look the same.
  • Race-by-Race Progression: Your research pool is divided evenly across the season. Earn your allocation of node unlocks at the end of every race, allowing you to reactively counter the competition and adapt your deck to upcoming track conditions.

• 🛠️ Developer Note

Lap by Lap is a solo-developer passion project built from scratch over several years. You can see the screenshot of the prototype running the  C++ core build before connecting it to Unreal Engine for the Visual Layer. By bypassing standard commercial engines, the entire game engine remains lightning-fast, ultra-lightweight, and fully optimized under 2GB. Thank you for playing the demo and supporting independent simulation devs!
