iRacing Season 2024 Week 1 Patch Notes

iRacing

With the start of competitive events of the new season, iRacing Season 1 2024 Patch 1 has been deployed. Here is a rundown of what is new.

iRacing‘s latest content update arrived 5 December at the start of 2023 Season 4’s Week 13, with plenty of new additions coming both with content and changes. Mugello was added along with the Audi R8 LMS Evo II GT3 and Slinger Speedway.

On the changes side, there are now 3D kerbs, AI Racing Improvements and even changes to surfaces when driving off-track. For everything you need to know about the latest title update, watch our video courtesy of our very own Emily Jones.

But the day after 2024 Season 1 officially began, you may have noticed there is a new update. Here is everything included in the 13 December update to iRacing.

iRacing Season 2024 Week 1 Patch Notes

In the simulation, shift lights have been fixed on a range of cars and also for those who do AI Racing, you will be happy to hear that the AI now hold their brakes after losing control. Seems many iRacing players could learn a thing or two from that.

Additionally, after 14 cars got the new damage model, two more have joined them, these being two classic Lotus Grand Prix cars in the form of the 49 and 79. There has also been improved audio levels to account for the addition of the 3D kerbs. Finally for Italian players, two new spotter audio packs are available.

The new Audi GT3 has gotten a lot of changes just after its release. Including its rear light initially coming on under braking, now has been changed to a rain light as was intended. Plus, the cockpit lighting would flicker when dynamic cubemaps were in use, which has been rectified.

Car and Track Changes

A few Dallara single seaters have had setups for certain tracks updated. The F3 car and both SF23’s baseline Mugello setups, the iR-01’s Daytona Road Course setup and the IR18’s Texas Oval setup have all been changed.

Additionally, there are a couple of cars that got the new damage model that had a few unintended features as a result. Examples include the Dirt Street Stock, Lamborghini Huracán GT3 EVO and SK Modified Car/NASCAR Whelen Tour Modified. Also the Legacy NASCAR Cup cars of the 2009 Chevrolet Impala, 2013 Chevrolet SS and 2016 Ford Fusion.

Then of course for tracks, this includes all the ones that either were added or saw changes in the latest title update. These being Mugello, Slinger Speedway and Okayama, a whole range of changes were made.

A variety of tarmac edge textures have been updated, and grass detail textures have been optimized for improved rendering performance. Visitor cars in the parking lots will now be correctly removed at lower graphics settings.

Fixed a variety of issues with incorrect off-track surface types. Fixed a feature where Barney, Legendary Flagman, would divinely levitate instead of using a worldly flagstand, when it was inadvertently hidden from view at lower graphics display settings. Fixed a track edge surface issue that could cause the Simulator to crash at night. Patched a small hole in the terrain near a Start/Finish wall.
