iRACING UI:

Licenses

- Official Events now have the ability to utilize and adjust the iRating and Safety Rating for a license class other than that which is required in order to qualify to join the Event. This cross-license information, if applicable, is provided in the UI via an additional license icon to the right of the qualification license.
- - For example, when an Indy Series that requires a C-Class Road License to participate goes to an Oval for Week 3, this specific event will now use your Oval iRating and Safety Rating for creating splits. When you're done racing, this event will also adjust your Oval License iRating and Safety Rating based on your performance.


Store

- A new sub-section has been added to the Store: Gift Cards!
- - You can find this sub-section in the Store section on the sidebar.
- - This sub-section takes you to a page where you may purchase iRacing Gift Cards for yourself or others.

- - iRacing Dollars may now also be purchased for yourself or others from the same page!

SIMULATION:

Race Control

- When a Race finishes under Caution, you should now receive the same pace order messages as you would under any other Caution. This may help to prevent unexpected penalties due to passing under a Yellow Flag after a Race has finished.

- Fixed an issue with new pit exit delay Race Control system where if the first and last cars on grid are on either side of the Start/Finish line, the grid traversal time would compute out to be negative instead of wrapping positive, resulting in a 2.0 second Pit Exit Hold Penalty for some racers.

- Fixed an issue where sometimes the gain-time penalties being displayed were astronomically miscalculated.


Track Surface Model

- New convection coefficient and solar constant calculations have been added.
- - In general, the track should retain more heat energy from cars as a result.


Road Racing

- When driving line aids are enabled, pit exit driving lines now appear for road courses that require any unique pit exit paths.

- - These setups were built as a new initiative to give all our Members an opportunity to be more competitive. They were created by iRacers from a variety of backgrounds including DWC drivers to well respected community setup builders. These setups should allow a driver with ample skill and seat time to be competitive in top split racing.

- - These setups were built as a new initiative to give all our Members an opportunity to be more competitive. They were created by iRacers from a variety of backgrounds including DWC drivers to well respected community setup builders. These setups should allow a driver with ample skill and seat time to be competitive in top split racing.
- - The “Notes” page within the setup has been updated to give parameter adjustment recommendations.

New Damage Model

- The New Damage Model is now enabled for the Dallara IR18!

- Detached vehicle parts and tires are no longer collidable shortly after they have been removed from a vehicle when using the New Damage Model.
- - This is a significant update, and has been made in the spirit of fairness for racers, as the differences between local machine processing for detached vehicle parts could lead to significant discrepancies between what a driver was seeing, and reality. This was leading to some drivers hitting invisible detached car parts, and other drivers passing clean through detached car parts, unaffected.
- - - Now, when a vehicle part detaches from a car, its collision properties are disabled 0.50 seconds after it is no longer touching another physical object, and it may then no longer interact with other physical bodies in the world, including cars.
- - - This system has also been implemented for track objects, such as cones. When a track object is moved from its home position, its collision properties are disabled 0.50 seconds after it is no longer touching another object, and it may no longer interact with other physical bodies in the world, including cars.
- - - - Track surface and terrain are excluded in these processes; objects always collide with the ground.
- - - - The 0.50 second cooldown for both vehicle parts and track objects is refreshed if contact is made with another non-ground object within the cooldown period.

- Colliding with detached car parts or tires no longer cause penalties to either the victim of the debris or the source of the debris during or after impacts. Penalties are still awarded for colliding with a vehicle that has parts missing, or for colliding with a vehicle that has parts hanging off.

- Collision polygons have been improved to mitigate snagging edges.
- - The object collision system uses a lower resolution polygon than the actual game object or surface for collision detection in order to reduce the triangle count and allow for faster processing. However, issues can arrise where two collision polygons meet and create a snagging edge. This change adjusts how these edges are calculated, smoothing them, and reducing the likelihood of creating snagging surfaces.

- For the New Damage Model, suspension and wheel damage repair algorithms have been updated in order to prevent unauthorized moon launches and provide a more accurate damage state.
- - Center springs and torsion bars now break along with the associated corner spring/damper. They also no longer break along with the wheel if only the suspension was damaged.
- - Repairing a damaged spring/damper no longer causes the car to jolt suddenly, due to the high degree of deflection, which could jolt the car uncontrollably, causing a moon launch, or, in many cases, re-break the suspension.
- - Reattaching a removed wheel also no longer causes a sudden jolt.

- Mount attachment positions for wheel tethers have been updated.
- - This fixes an issue where tethered wheels could get into odd spots if they were dislocated due to a heavy impact prior to detachment.

- When a vehicle part detaches, the total breaking force is no longer applied directly to the car part, as this was far too large in some cases.

- Fixed a potential SIM crash issue that could occur when suspension damper rates were beyond safe limits.

- Fixed a potential SIM crash issue that could occur when the meshes involved in a collision test included too many overlapping triangles. This could occur with multiple complex objects, or at very high speeds.

- Fixed some issues with shadows for detached car parts.

- Fixed an issue where opponent and AI cars could make scraping sounds while driving around normally.


Old Damage Model

- Collision incident reporting has been updated for the Old Damage Model so that world impacts check for if the surface is a non-racing material before reporting an incident.


Pit Stop

- The animation system has received some optimization.

- Fixed an issue where sometimes a pit crew member failed to animate.

- Fixed an issue where the tire assistant pit crew member could get stuck in a T-pose.

- Fixed an issue where pit crew tires were missing if their team's car was not in the world.

- Fixed an issue where wheels were disappearing in virtual mirrors during pitstops.


Rendering

- Fixed an issue where flags could be showing ghosted and stationary shadows.

- Fixed an issue with flickering shadows at night.

- Fixed an issue where certain catch fences and trees incorrectly reflected sunlight from transparent areas.

- Fixed an issue where static shadow maps were not rendering darkness correctly on very large objects, such as terrain and grandstands.


Lighting

- Ambient night lighting has been adjusted. Overall lighting and shadows should be a bit darker.

- Stadium lighting on smoke and dust puffs has been improved.


Visual Effects

- Fixed an issue where concrete impact effects persisted too long.


Audio

- All NASCAR vehicles have had their in-car engine sounds updated.

- A new switch, "xa2_mixToLFE=1", has been added to the [Audio] section of the "app.ini" file.
- - This switch allows users to disable mixing normal game audio to the LFE channel on the default sound card. This can be used to stop game audio from interfering with our LFE bass shaker effects if both are outputing on the same audio channel.


Controls

- A new method for detecting XInput has been enabled for joysticks.

- The "joyEnableVibratePedalBinary" setting has been replaced with new "joyVibratePedalMinPct=10" and "joyVibratePedalMaxPct=90" entries within the "[Force Feedback]" sectio0n of the "app.ini" file.
- - These new entries let you set the minimum amount of lockup before the pedals start to vibrate and the maximum amount of lockup beyond which the pedals will vibrate at 100 percent. Based on your settings, if your pedals vibrate too often, then raise the minimum value, and if the vibrations are too weak, then lower the maximum value.
- - - The old binary mode had both values set to 30 percent, if you wanted to simulate the previous behavior.
- - - Please also note that this affects not only pedal vibration but also wheel and game pad vibration if your devices support that.


Spotter

- A Russian spotter pack has been added to iRacing!
- - Support for this pack was provided by Dmitry Eniseev.
- - For now, this is an audio-only spotter pack because the Simulator currently does not support the display of Cyrillic characters.


Video Capture

- The latest D3DGear video capture API has been updated.
- - This fixes a lock-up at shutdown that some users were experiencing.

Cedar Lake Speedway

- NEW TRACK!
- - Cedar Lake Speedway, a Dirt Oval track, is now available for racing!
- - - Home of The Masters and the USA Nationals, Cedar Lake Speedway is one of the premier circuits on the World of Outlaws Morton Buildings Late Model Series schedule. “Wisconsin’s Fastest Piece of Real Estate” is a .375-mile clay oval based in New Richmond, Wisconsin, that broke ground in 1956 and opened the very next year. The track was conceived after farmer Elmer Cook remarked that the natural bowl in the swamp on his farm property would make a perfect racetrack, and after just three weeks of roughed out work, the track began to take shape. Since then, Cedar Lake has come a long way from its humble beginnings, which saw 85 spectators watch 12 cars at its first event. Today, it’s home to marquee events like the World of Outlaws USA Nationals, The Masters, Legendary 100, and more. Whether sprint cars, late models, or modifieds are your preference, you’ll find Cedar Lake’s clay surface to be as fun as it gets to drive.

Long Beach Street Circuit

- FULLY UPDATED TRACK!
- - Long Beach Street Circuit is officially no longer a Tech Track! A complete 3D environment has been built around the existing laser-scanned asphalt road track!
- - - Born against long odds in 1976, the Long Beach Grand Prix is North America's premier street race. The debut event featured Formula 5000 cars in a race won by Brian Redman. The following year, Clay Regazzoni captured the inaugural U.S. Grand Prix (West) and in 1977 Mario Andretti passed Jody Scheckter in the closing laps to become the first American to win an F1 race on home ground. Andretti's popular victory put the race on firm financial footing and set in motion the rebirth of Long Beach, which morphed from a down-on-its heels port city to a thriving modern city/tourist destination. The resulting building boom necessitated ongoing changes to the track layout, finally settling on the current 1.968 mile, 11 turn circuit encircling the Long Beach Convention Center and the Long Beach Aquarium. Nor were the changes limited to the track and its environs. The Long Beach GP changed gears in 1984, bringing the home-grown Indy cars to town as the featured attraction. The event hardly missed a beat, as the names of Unser, Zanardi, Montoya, Franchitti and Power soon joined the likes of Regazzoni, Andretti, Villeneuve, Piquet and Lauda on the illustrious list of Long Beach winners. What's more, the event grew to include - at various times - the American Le Mans Series, GRAND-AM Sports Car Series and the Pirelli World Challenge, along with the popular Toyota Celebrity race in which Hollywood's famous (and near famous) exchange Armani and Gucci for Simpson and Bell. F1 or IndyCar, world class driver or movie star, the Long Beach Grand Prix circuit is as testing as they come ... with very hard walls eagerly awaiting the slightest mistake.
