[/p][h2]SIMULATION:[/h2][p]--------------------------------------------------------------[/p][h3]Graphics[/h3]

[/p][p]This Patch Release contains updates and fixes for the 2025 Season 3 Release.[/p][p]

[/p][h2]iRACING:[/h2][p]--------------------------------------------------------------[/p][h3]Flags[/h3]

• [p]Fixed an issue where some Race Results would display a customer's previously selected Flag instead of the Flag they had selected at the time of the event.[/p]
  • [p]Results preserve the flag participants were flying at the time of event entry as historic data.[/p]
  • [p]This was especially noticeable for customers attempting to use our recently added flags for the countries of the United Kingdom: England, Northern Ireland, Scotland, and Wales.[/p]

[p][/p][p][/p][p][/p][h2]SIMULATION:[/h2][p]--------------------------------------------------------------[/p][h3]Licenses & Official Racing[/h3]

• [p]Adjusted the distribution of iRating and ttRating values that define Division separation for all Official Racing and License Classes for improved competition at all levels.[/p]
  • [p]We had tuned the division distribution slightly with the start of 2025 Season 3, and we missed the mark by a bit. This second adjustment should clean things up and improve Ranked participation.[/p]
  • [p]With the deployment of this Patch, all members will be redistributed into Divisions for all licenses classes, just as is done seasonally before Week 1. This redistribution will be completed based on drivers’ iRating, ttRating, and Rookie status as they were a few weeks ago when divisions were first established during the 2025 Season 3 season transition. Drivers are not being redistributed based on their current iRating, ttRating and Rookie status. All previous 2025 Season 3 records, stats, and results will follow their owners into their new Division.[/p]

• [p]iRacing setups have been updated.[/p]
