Web Data API
Results / Get
– – Added ‘strength_of_field’ and ‘num_entries’ to each car class in the event results for the class SoF and entry count.
– – Removed ‘simulated_start_utc_time’ and ‘simulated_start_utc_offset’ from results “weather” object, and added ‘simulated_start_time’ to be consistent with Weather objects in other areas of the API.
Series / Seasons
– – Removed duplicate ‘simulated_time_multiplier’ from schedule objects. Now only appears in the “weather” object in each schedule.
– – Removed ‘simulated_start_utc_time’ from the schedule “weather” objects.


Race Servers
Improved validation for allowing or disallowing rolling starts based on the selected track for an event.

AI Racing
AI Drivers have improved their wet racing lines on a variety of tracks, especially for heavy rain.
Fixed an issue when AI Drivers would sometimes space out at Superspeedways, and forget to leave the pit or grid stall.
Fixed an issue with various Asphalt Oval cars that could cause the Simulation to crash when AI Drivers were using some final drive ratios at the iRacing Superspeedway.

iRacing Weather System
Updated the visual effects for rain running up a windshield. This stops droplets from disappearing before they physically leave the windshield.
Fixed an issue where rain effects could sometimes be visible when watching Replays when it’s not raining at the current timestamp.
Improved how windshield wipers operate during Replays
Improved how wet and dry states for windshield wipers progress based on vehicle velocity and the wet/dry state of the Session.
Fixed an issue where aerospray could appear blocky when HDR was disabled.
Improved the wet/dry appearance of the windshield during Replays, particularly when rewinding or transitioning through wet/dry states.
Fixed an issue where windshield wipers were not clearing water correctly when manually activated while auto wipers were disabled.
Fixed an issue where the times used by visual effect calculations for windshields could become incorrect.

Fixed an issue where opponent cars could appear to have the incorrect wing angle settings based on what the driver had set.

An update has been made that shows evidence of avoiding the widely reported GPU crashes that started with the 2024 Season 2 Release.
– – We have added a mechanism to disable SMP/MVP/SPS only for the particle effects system code (PopcornFX). Some evidence shows these processes interacting with PopcornFX systems may be triggering the GPU crashes reported shortly after the release of the iRacing Weather System.
– – With this Patch 2 Release, those special Nvidia-only modes (SMP/MVP/SPS) bypass the PopcornFX system. These modes are still fully enabled for all other rendering. This change should have a minimal impact on performance processing and framerate.
– – – – Should you wish to override this new default, you can find two new values in your appropriate “rendererDX11*.ini” file: “PopcornFXSPSAllowed” and “PopcornFXSMPMVPAllowed”. Setting both to “1” re-enables the special Nvidia-only modes for the particle effects system.
Fixed an issue where full-resolution particle effects were not appearing correctly in the top-left quadrant of the screen.

Fixed an issue where Replays could fail to load if they included a driver who registered but failed to join the Session.

Support for Conspit pedal vibration has been added.
The latest Simucube API has been integrated.
Fixed an issue where Force Feedback was not being properly enabled when the setting: “enable360HzInterpolated=0” for Simucube wheels.

The race server name is now logged in the Session string.
