Forza Motorsport Update 15 began rolling out on December 9, 2024, for Xbox Series X|S and PC via Microsoft Store and Steam. It added a four-week Australia-themed event period, optional PC-only ray-traced global illumination (RTGI), multiplayer upgrade tools and changes to Safety Rating and race regulations. The Australia events were announced to start December 11, 2024, at 4:00 p.m. PT (December 12 at 00:00 UTC), so those dates and events are historical rather than a claim of current availability.

What Update 15 added

Turn 10 Studios announced Update 15 on December 9, 2024. Its major additions covered Australian-themed Career and Featured Multiplayer events, PC lighting options, and adjustments to multiplayer and race rules. The update was the studio’s final content update of 2024, according to that announcement; its preview of Update 16 for January 2025 was a plan stated at the time, not an indication of the game’s current update status.

Australia Tour and Forza AUS Series

The announced four-week Australia Month paired two distinct activities: an Australia Tour in Career and the Forza AUS Series in Featured Multiplayer. Both brought Australian cars and Mount Panorama into focus, including sport utes and V8-powered supercars. Turn 10 described Bathurst—Mount Panorama’s circuit—as exclusive to Forza AUS during Australia Month. The publisher gave the circuit’s length as 3.8 miles (6.2 km) and its elevation change as 570 feet (174 meters).

The event period was temporary. The announcement does not establish that Australia Month, its events or any associated unlocks remain available now; check the current game for what is playable.

Optional, PC-only RTGI

Update 15 added Ray-Traced Global Illumination to the PC versions of Forza Motorsport. Turn 10 said the feature uses ray-tracing hardware to calculate indirect lighting and occlusion across cars and tracks in real time. It applies in gameplay, cinematics, Homespace and Photo Mode, and is off by default. Xbox Series X|S did not receive this RTGI setting.

To enable it on PC, open the game’s graphics settings and select Raytracing Quality: Full Reflections + RTGI, then set RTGI Quality: High. Turn 10 described RTGI as intended for high-end PCs, but did not publish a minimum GPU model or a quantified performance cost. The visual feature may involve a performance trade-off; the announcement gives no measured frame-rate figures, and PC transition behavior can vary by system.

Multiplayer and Safety Rating changes

Upgrades during eligible events

Eligible Featured Multiplayer series gained access to Custom Upgrade and Quick Upgrade within events. Turn 10 named Open Class, Cycled Class and Multi-Class series among those affected. This lets players adjust a car’s build for an eligible event without leaving the event flow.

More races inform Safety Rating

Turn 10 increased the number of races used in the Safety Rating calculation from 20 to 50. The stated aim was to reduce severe rating swings and better represent a player’s broader race history. This is a change to the calculation’s input window, not a promise that an individual rating will rise or fall by a particular amount.
