DynaXF Technology is our next-generation vehicle dynamics simulation engine, developed to deliver a level of realism, precision and determinism that goes beyond the limitations of traditional physics engines used in video games.

​

Instead of relying on simplified approximations, DynaXF reproduces the complete behavior of a vehicle using multibody physics models, simulating suspension systems, tires, transmissions, steering systems, differentials, sprung and unsprung masses, weight distribution and dynamic load transfer.

The result is a platform designed for both professional simulation and high-end commercial driving simulators.

​

Built on Project Chrono

​

DynaXF uses Project Chrono as its physical simulation core.

​

Project Chrono is one of the world's most advanced multibody dynamics simulation engines, developed over more than two decades and used by universities, research institutions, manufacturers and international organizations for vehicle research, engineering and validation.

​

Rather than developing a physics solver from scratch, DynaXF leverages Chrono's computational capabilities and builds a completely new software architecture specifically designed for real-time vehicle simulation.

​

More Than a Physics Engine

​

Chrono provides the simulation. DynaXF transforms that simulation into a complete vehicle dynamics platform.

​

Built on top of Project Chrono, DynaXF introduces an entirely new software architecture featuring:

​

• Deterministic real-time runtime

• Native Unreal Engine 5 integration

• Modular vehicle architecture

• Public developer API

• Advanced hardware input management

• High-fidelity Force Feedback

• Professional telemetry system

• Deterministic replay system

• Architecture designed for commercial and industrial simulators

​

All while maintaining a complete separation between the rendering engine and the physics engine.

​

Designed for the Future

​

DynaXF has been designed so that the physics engine can evolve independently from the rendering layer.

​

This allows the same simulation core to power:

• Racing simulators

• Truck simulators

• Heavy machinery simulators

• Military vehicle simulators

• Bus simulators

• Industrial vehicle simulators

• Research and development platforms

• Professional training simulators

• ​

Every vehicle shares the same underlying technology, reducing development time while ensuring consistent behavior across the entire platform.

​

Precision Without Compromise

​

One of the fundamental principles behind DynaXF is determinism.

The simulation runs using a fixed timestep that is completely decoupled from the graphics engine's frame rate, producing repeatable and consistent results regardless of rendering performance.

This architecture enables reliable physics validation, reproducible telemetry, and the development of advanced control, analysis and testing systems.

​

Open Engineering Built on Proven Technology

​

We believe innovation is not about reinventing proven technologies, but about building on them.

 

That is why DynaXF combines the scientific foundation of Project Chrono with a software architecture developed entirely by Come Over Gaming to meet the requirements of modern professional vehicle simulation.

​

The result is a platform that brings together scientific research, engineering and real-time simulation within a single ecosystem designed for the next generation of driving simulators.
