SIMULATION:

————————————————————–

Optimization

• Improved rendering performance for complex scenes, such as during gridding.

Updater

• Several pieces of Rookie content have been added to our REQUIRED downloads list in preparation for a short new player onboarding experience planned for release within 2024 Season 1. These items include:
• – – Formula Vee
• – – Street Stock
• – – Lime Rock Park
• – – USA International Speedway

Physics

• A new 3D curbs system has been added to a select group of tracks!
• – – The new 3D curb system fully models all curbing at the track, including small curbing previously simulated via a texture. These new fully 3D object curbs allow for a much greater sense of realism for running over curbs and tire interaction. The following tracks now utilize the 3D curbs system:
• – – – – Autodromo Internazionale del Mugello 
• – – – – Okayama International Circuit
• In some areas at some tracks, the lateral distance from the track edge for porous surfaces now increases the rolling drag applied by that surface, simulating an increase in depth of the loose off-track surface. Generally, porous material surfaces start out shallow near the track edge and get deeper the farther from the track surface you travel.
• Grass, dirt, sand, and gravel have had improvements to the feeling of surface displacement.
• For grass surfaces, peak shear strength has been reduced slightly when a tire is slipping.

Race Control

• Fixed an issue where your Average Lap Time in a Practice Session was incorrectly including incomplete laps, for example where you reset to your pit stall.

Oval Racing

• iRacing is happy to release Phase 1 for our Asphalt Oval Refresh Project.
• – – Asphalt Oval Refresh is an ongoing project with the aim to improve the overall experience and realism of asphalt oval racing. This release of Phase 1 includes improvements to the surface grip levels as it relates to surface temperature. This should provide a more dynamic experience overall with factors such as weather, car count, and where cars are running on the track.
• ALL Oval track configs (Asphalt, Dirt, large, small, tri-oval, etc.) now calculate drivers’ SR adjustments based on a factor of 4 corners per lap. Previously, many small Ovals were using a value of 2 corners per lap, which would make penalties more punishing for races of similar lengths than those at larger ovals. This change will help equalize the SR playing field between Oval drivers who prefer small or large oval racing.

AI Racing

• AI Racing is now available with the following new cars:
• – – Audi R8 LMS EVO II GT3
• – – HPD ARX-01c

• A new asphalt road racing track, Autodromo Internazionale del Mugello, is now available for purchase and racing!
• – – After half a century’s worth of events on public roads were brought to an abrupt halt in 1970, Autodromo Internazionale del Mugello was constructed in 1973 and opened a year later to bring premier racing events back to the area. It quickly became host to major sports car events, lower-level open-wheel series, and grand prix motorcycle racing, for which it has hosted the Italian motorcycle Grand Prix for the past 30 years. In the COVID-19 impacted 2020 World Driver’s Championship, it hosted the series for the first time with the Tuscan Grand Prix. Mugello features two layouts: its 3.259-mile, 15-turn Grand Prix layout, and a 1.4-mile Short configuration. Both start with its lengthy front straightaway and go into the 180-degree San Donato right-hander before heading into Luco and Poggio Secco. The track has been owned by Scuderia Ferrari since 1988, which uses it for both testing and the Ferrari Challenge Finali Mondiali; the Tuscan Grand Prix in 2020 marked its 1000th Grand Prix event.
• Autodromo Internazionale del Mugello includes two track configurations: Grand Prix & Short
• Add Autodromo Internazionale del Mugello to your virtual landscape by purchasing it from the iRacing Store!

Slinger Speedway

• NEW TRACK!
• A new asphalt oval track, Slinger Speedway, is now available for purchase and racing!
• – – Known as the “World’s Fastest Quarter Mile Oval,” Slinger, Wisconsin’s Slinger Speedway is the quintessential bullring short track. Opened in 1948, its defining characteristic is its high-banked corners, which reach an imposing 33 degrees on each end. That steep banking allows racers to post blazing fast laps, including Jeff Bloom’s 9.908-second time in 2010-the first quarter-mile oval lap record in history to break the 10-second barrier. Formerly a flat, clay track, Slinger was reconfigured for the 1974 season into its current paved and high-banked state. Its most famous race each year is the Slinger Nationals, a 200-mile Super Late Model race that has been won by some of the biggest names in short track racing and NASCAR alike; former Cup Series champion Matt Kenseth holds the record with eight wins between 1994 and 2019. Slinger also has a paved X running through its center to host Figure 8 events.

My Take

A lot of good stuff this time around.

The Good

I’m stoked for the improvement to the dynamic track surface. That one has been a long time coming especially because previously we had it and it worked well with the 6th Gen tire model. Unfortunately when they updated to the latest tire model (7th Gen) it irrevocably broke the dynamic track.

The track would still change going from sun to shade or vise versa but rubber build up and changes from the cars over a race no longer worked. Supposedly this has been fixed. Fingers crossed!

I’m a little confused why they have bothered to bring the new damage model to the retired (Legacy) cars? Unless they have some sort of plan to do something with the previous generations of cars bothering to port the new damage model to them seems like a waste of time. Or at least time that could have been much better spent somewhere else on the oval side?

I fail to see the point of updating the damage model all of the way back to the COT (5th Gen) or the previous Trucks? I guess the COT is used in Draft Master Series for 2 weeks out of a whole season. But the old Craftsman Trucks Series vehicles?

The Bad

The bad is really bad this time.! They’ve finally done it. The Legacy Membersite is losing its functionality. I don’t have the words to describe how much I hate using the “iRacing UI.” The nicest thing I can say about it is that is sucks, kinda does what the legacy site does only worse in every way, and if it were a dog or a horse I would take it out back behind the barn and put it out of everyone’s misery.

Literally the only defense I have heard of it centers around things that were added exclusively to it. It has no redeeming qualities whatsoever. How hard can it be to take the current races page from the old site, wrap it in an iFrame, or Java Applett, or a damn Flash file and let us actually see what is running when and how many entrants there are?

How to fix it? Well that’ll require a few things. I’ve made a handy list:

• Some rope
• 2 minimum, but preferably 4 horses
• A whip or switch
• Someone good at knots
• Someone with a strong stomach
• Whomever was responsible for that abomination
• Someone with at least a passing familiarity with the medieval practice of draw and quartering

That was my second choice, I decided to pass my first choice because linking to an ISIS training manual could be considered poor taste in some circles.
