When it comes to sim racing, few titles are as iconic as iRacing. Over the years, it has built a reputation for its highly competitive racing environment, diverse roster of vehicles, and unparalleled focus on realism.

A standout feature of the simulator is its damage model, designed to replicate real-world crashes and car behavior under stress.

However, for all its strengths, the iRacing damage model has faced significant criticism for its collision physics and netcode issues.

In this article, we’ll dive deep into the evolution, strengths, and shortcomings of the iRacing damage model, exploring why it remains a hot topic in the sim racing community.

A Look Back: The Evolution of the iRacing Damage Model

The Early Days (2008)

When iRacing launched in 2008, it was a game-changer in the world of racing simulators. Unlike many arcade-style games, iRacing took simulation seriously, offering a damage model that was far ahead of its time. The system aimed to simulate not just visible damage but also the structural and mechanical consequences of collisions. For sim racing enthusiasts, this attention to detail was a breath of fresh air.

Back then, vehicles in iRacing could show signs of wear and tear from crashes, with components like fenders and bumpers visibly deforming upon impact. This was a significant step forward compared to other simulators of the era, which often ignored damage entirely or treated it as an afterthought.

Progress Over 15+ Years

Fast forward to today, and iRacing has only improved its damage model in terms of visual fidelity. The way cars deform after a collision is impressively realistic, with shattered parts, crumpled metal, and even pieces flying off vehicles. These visuals add a layer of immersion that enhances the overall experience.

However, despite this progress, core issues with collision physics have persisted. While the damage looks more realistic, the way vehicles react to contact remains largely the same as it was in 2008.

Unpacking the Flaws in the iRacing Damage Model

Collision Physics: The Unrealistic Side of Realism

One of the most common complaints about the iRacing damage model is its overly sensitive collision physics. Even minor touches between cars can have catastrophic consequences, often described by players as feeling like hitting a landmine.

For example, a slight brush against another car’s side can send both vehicles careening off the track, with damage so severe that it feels disproportionate to the impact. What’s more, these reactions often ignore the weight and size of the vehicles involved. Lightweight cars can overpower much heavier ones in collisions, leading to unrealistic outcomes that break immersion.

Another frustrating issue is the lack of recovery options. In real-world racing, drivers can often correct their trajectory after minor contact through countersteering or adjusting their grip. In iRacing, however, such incidents often spiral out of control, leaving players with little chance of recovery.

Netcode Problems: Invisible Hazards

Another notorious issue with the iRacing damage model is the so-called “netcode.” This refers to how the game predicts the position of cars in online races, accounting for differences in internet connection speeds. While netcode is essential for smooth multiplayer gameplay, it often leads to bizarre incidents where cars collide without actually making contact.

These phantom collisions are not only frustrating but can also ruin competitive races. Imagine fighting for position in a tight corner, only to be sent flying by an invisible force. This has been a long-standing issue in iRacing, and despite incremental improvements, it continues to be a major source of frustration for players.

Limited Tolerance in Close-Quarter Racing

Close-quarters racing is a hallmark of motorsport, but in iRacing, it often feels like a gamble. The damage model is so unforgiving that even light body-to-body contact can end a race. Modern car bodies are designed to absorb impacts and protect their structural integrity, but iRacing’s vehicles often behave like billiard balls, bouncing off each other in exaggerated ways.

This lack of tolerance discourages aggressive but fair racing, forcing players to adopt overly cautious strategies. For a simulator that prides itself on realism, this is a significant disconnect from the real-world racing experience.

Strengths of the iRacing Damage Model

While the collision physics leave much to be desired, the visual aspect of the iRacing damage model is undoubtedly impressive. The way cars deform under stress is a testament to the developers’ commitment to realism. From crumpled fenders to shattered windshields, every detail adds to the immersion, making crashes feel authentic and impactful.

This visual feedback also serves a practical purpose, helping players understand the consequences of their mistakes. For instance, a damaged front wing will not only look realistic but also affect the car’s aerodynamics, forcing players to adapt their strategy.

Despite its flaws, iRacing remains a benchmark for damage models in the sim racing genre. Few titles offer the same level of visual detail and mechanical realism. This sets iRacing apart from more casual racing games, which often ignore damage entirely.
