2024 Season 3 Patch 2 is live and ready for racing!

========================================================================

This Patch Release contains a variety of updates and fixes for the 2024 Season 3 Release.
This Patch includes the release of the Oswego Speedway - Dirt track configuration!
This Patch also includes an update on the widely reported GPU crashing issues that started with the 2024 Season 2 Release.



--------------------------------------------------------------
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.

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

Graphics
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.

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

Controls
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.

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

===============================================

This Patch Release contains important updates and a few fixes for the 2024 Season 2 Release.
Of special note, this Patch removes EasyAntiCheat (EAC) as our Anti-Cheat Software provider and restores Epic Online Services (EOS) to this designation. Issues that resulted from this initial change at the beginning of 2024 Season 2 have been resolved. No actions are required from our Members to make this switch.

- - The pit crew now immediately recognize when tire checkboxes have been changed, and immediately start a pitstop when a tire compound change is toggled. When the checkbox changes, it is now immediately effective, more like how a black box operates.
Improved some pit stop detection scripting.

Spotter
Your spotter’s visual acuity has been improved, and he will now let you know if you’re using the wrong tire compound for the current wetness conditions while you are gridding instead of after the race has started.
When you jump the start of a race, the spotter will no longer inform you of the exact duration of your hold penalty, because he was often incorrect due to its variability.
The spotter call for having a car in front or behind you pitting may now only be called once every 10 seconds.

2024 Season 2 Patch 2 Hotfix 1 Release Notes [2024.04.02.01]


This Patch Release contains dozens of updates, improvements, and important fixes for the 2024 Season 2 Release. This Patch also includes several additional key updates, including:
Two new “Outlaw” models have been added for the Dirt Micro Sprint Car!
The Ford GT GT3 and the McLaren MP4-12C GT3 are rain-ready!
The SRX is AI Enabled!
The Maximum allowable rain rate is now capped for Official Fixed Setup Series Racing.

We continue to investigate and work towards fixing several other high-priority issues.


--------------------------------------------------------------
Weather
A new filter, “Rain Allowed,” is now available on both Official and Hosted Racing pages.
Fixed an issue where the wind speed values advertised in weather information always displayed as kmph regardless of user preferences.

Test Drive
Fixed an issue where trying to launch a Test Drive populated directly from an Official Series that changes cars each week (Ringmeister and Draft Master) was not selecting the correct car.
The Test Drive button in iRacing Web now offers to launch iRacing instead of failing to launch Test Drive.

Official Racing
The Forecast graph now correctly displays the Session time bars in the graph.

Hosted Racing
The Hosted Races table now caches the selected filters, sorts, and page number for browsing Sessions and for viewing your own created Hosted Sessions. This allows you to pick up where you left off when returning to the page.

Create A Race
For Open Setups, Setups are now listed in alphabetical order.

Spectate
Fixed an issue where the Spectate page did not properly indicate which tab the user was on in some situations.
The Spectate Hosted Races table now caches the selected filters, sorts, and page number for browsing Sessions. This allows you to pick up where you left off when returning to the page.
- - This functionality remains in development for the Official & League tabs of the Spectate page.

Results & Stats
Removed an erroneous cancel icon from the date range filters.

--------------------------------------------------------------
iRacing Installation
A checkbox has been added to “Launch iRacing” after completing a new installation.

Race Servers
Fixed a critical issue where the new physics “zippy” crash logging code could cause a Race Server to crash.

Physics
Some additional checks and controls have been put into place which immediately remove a vehicle from the world if its physics values appear to be ramping unrealistically fast, which could lead to causing a “zippy” event. These checks stop these abnormal physics events from reaching the Race Server and prevent it from crashing multiple players simultaneously.
- - With this security measure in place, a user that would have experienced a zippy event, perhaps getting launched to the moon, is instead dropped from the race server and a crash dump file is created. To other drivers, this user will appear to have disconnected. Since their physics information is prevented from reaching the Race Server, all other drivers in the Session are protected from it attempting to process unrealistic values, and the Race Server will continue to run normally.

iRacing Weather System
The maximum allowable rain rate in Official Fixed Setup Sessions is now capped at a rate which is heavy enough to strongly encourage drivers to shake up their driving, but not so strong as to ruin the Fixed Setups racing experience.

Some raindrop textures have been updated.
Opponent car windshield effects have been updated.
The aero spray effects coming from cars has been updated.
Improved the process for wind speed calculations for Forecast Weather Mode.

Graphics
When loading into a Session where rain and/or wet racing could occur, a new warning message now appears to inform users if they do not have their Graphics Quality set high enough to render rain and wet effects properly.
Fixed a graphical bug that could cause a sliding shadow effect on objects when SSAO was enabled.
Some vehicle carbon fiber textures have been adjusted for improved shader processing.

Spotter
Added spotter messages when gridding that tell you when half the field has gridded, and when five, two, and one cars remain to be gridded.
The spotter will now always countdown to your pit box if the countdown option is enabled, regardless of what Spotter Chattiness Level you have selected.
The Lap Time and Pit Service Finished spotter messages no longer play if the Race is over.

Active Reset
Opening the Options Menu now invalidates any Active Reset save state.
- - This prevents changing settings like shift mode that can invalidate the car's state.
Fixed an issue where the Active Reset sounds were not playing correctly.

Controls
Simagic Haptic Pedal Reactor support has been re-enabled.
For Simucube wheels using the new 360 Hz API, the [Force Feedback] “forceResetBeforeStartup” option is now disabled by default.
For Force Feedback, the automatic calibration will now take the track surface wetness into consideration and will slightly reduce the maximum forces for wetter sessions.
Fixed an issue with the new clutch launch control.
- - This system now properly resets after the end of a launch, rather than remaining active for 5 seconds. Also, a new switch to change the mode from a “press-and-release to launch” to a “press-and-hold to launch” has been added to the “app.ini” file; This is named [Force Feedback] clutchLaunchMode=0.

Telemetry
Reworked the “irsdk_PitCommand_TC” command to be zero-based rather than one-based.
