2025 Season 4 Patch 3 Release [2025.10.16.01]

2025 Season 4 Patch 3 Release Notes [2025.10.16.01]

This Patch Release contains important updates as well as fixes for issues with the 2025 Season 4 Release.

Special Demo Drive Note:

• During this maintenance period, there will be intermittent connectivity to the Demo Drive launching/setup service for roughly the first 30 minutes of downtime. Customers who enter a Demo Drive Session during this period will be unaffected by the ongoing work. After the Demo Drive work is complete, and our patch deployment process continues as normal, Demo Drive will be fully functional again as usual.

• Since Demo Drive will not be fully available during this maintenance period, Demo Drive will be left up for 24 hours once maintenance is complete.

Simulator

Physics

• Track splines are now aware of their relative altitude and may factor this parameter into predictive and estimated calculations related to car types for things such as estimated laptimes, race control gained time yield behavior, penalty balance, and more. This will improve timing functionality not only at a high altitude track, like Mexico, but will also improve a track that has significant altitude variation throughout its run, like Mount Washington.

• Parameters for vehicle turbo and boost have been adjusted to correspond better with the latest updates for realistic engine operation at altitudes. These changes impact the following vehicles:

  • GT3

  • GT4

  • GTE

  • Touring Cars (TCR)

Race Control

• Fixed an issue where black flags were given for course cuts that were not committed.

AI Racing

• AI Drivers have improved their racing skills with the GT4 and GTP class cars to coincide with the hybrid system updates.
