Forza Motorsport Update 15 Release Notes

9 December 2024- Turn 10 Studios
Car passion is deeply rooted in Australia. Celebrate its racing heritage over the next four weeks with Australia Month in Forza Motorsport.

Over in Career, the Australia Tour is where you will experience the storied legacy of Australian motoring culture: from the iconic Mount Panorama Circuit, where the legendary Bathurst 1000 endurance race unfolds amidst breathtaking scenery, to the Australian-made sport utes that seamlessly blend speed and utility.

Compete in high-performance V8-powered supercars in the Forza AUS Series in Featured Multiplayer, featuring Bathurst exclusively for the duration of Australia Month. Rolling Starts expand to additional Spec Series, while the Nordschleife and Nürburgring – Full Circuit have been added to select Open Series events.

Update 15 also introduces the ability to upgrade cars in Featured Multiplayer Open Events, faster transitions in Spectate and Replay, changes to Safety Ratings, and Ray-Traced Global Illumination (RTGI) for players on high-end PCs.

Ray-Traced Global Illumination on PC (RTGI)

  • A new graphics option for our PC players has been added to Forza Motorsport's ray tracing settings to enable Ray Traced Global Illumination in game (RTGI for short).

  • RTGI uses ray tracing hardware to compute more accurate indirect lighting and occlusion across the track and car in real time. This results in enhanced visual fidelity and realism in the game.

  • RTGI can be enabled in the Forza Motorsport Graphics menu using the following toggles:

  • Set Raytracing Quality to "Full Reflections + RTGI"

  • Set RTGI Quality to "High"

  • When enabled, RTGI will apply to all gameplay and cinematics, as well as your Homespace and Photo Mode.

  • RTGI is a new setting that must be enabled and is not on by default. If you require assistance with turning on RTGI on your PC, please see this article.

Upgrades in Featured Multiplayer

  • Custom Upgrade and Quick Upgrade functionality are now accessible from within Featured Multiplayer events for Series that allow it, including all Open Class Series, Cycled Class Series, and the Multi-Class Series.

  • This makes it easier than ever to tweak your current build without needing to leave the event or experiment with a new setup before the race starts. Additionally, this improves visibility for any PI Limits that may be in place for the current event.

Faster Transitions in Spectate & Replay

  • Transitional black loading screens when switching camera types and cars on focus in both Spectate and Replay have been replaced by quick fades wherever possible, closer to the blink of an eye. [1874035]

  • Loading screens will only appear when changing streaming zones, such as jumping from one end of a long track to another. For PC players, this experience may vary based on system specs.

Safety Rating Updates

We have adjusted the impact of recent races on your Safety Rating to reduce severe rating fluctuations and to more accurately reflect your overall race history.

We have also increased the number of races used to calculate your rating. Previously, we increased the number of races from 10 to 20 and saw positive results. In this update, this number is further increasing from 20 to 50.

Update 15 introduces a new model for Forza Race Regulations (FRR). This version brings a slight reduction to false positive penalty assignments, takes tire wear into account when computing time gained for off-track penalties, and fixes an issue where the player could be disqualified by going off track prior to crossing the Start/Finish line.

Today’s update also includes enhanced car audio for the following vehicles:

  • 1991 BMW M3
  • 1994 Ferrari F355 Berlinetta
  • 2013 Ferrari La Ferrari
  • 2015 Ferrari F12 TDF
  • 2017 Ferrari 812 Superfast
  • 2015 McLaren P1 GTR
