With their 2023 Season 4 Patch 2 this week iRacing added the Honda engine variant for the Super Formula SF23, allowing users to select from Toyota or Honda. If you do not own the SF23 then it is a single purchase to get both variants. Even with the surprise car engine, this is a normal build, with an array of fixes you can read about in the build notes below.

Their text:

The Honda-powered edition of the Super Formula SF23 is now available on iRacing! It joins the Toyota-powered version of the car, which was released with the deployment of 2023 Season 4 content earlier this month. Both the Honda and Toyota versions of the SF23 are included in the same content package, so users who have already purchased the Toyota will receive the Honda automatically, and users who purchase the SF23 moving forward will receive both cars.

Debuting in the 2023 Super Formula season, the SF23 is the third open-wheel car developed by the Italian manufacturer Dallara for Japan’s premier open-wheel racing series. From a visual standpoint, the SF23 evolves from its predecessor by introducing new aerodynamics designed to produce more overtaking. From a sustainability one, the new design reduces carbon dioxide emissions in raw materials and manufacturing by 75% thanks to new, natural materials, while even the Yokohama tires used on the car use significantly more renewable raw materials while maintaining the performance of previous tires.

Super Formula cars are powered by high-performance, turbocharged 2.0-liter I4 engines built by Honda or Toyota, each capable of producing more than 540 horsepower. Each is equipped with a push-to-pass overtaking system that allows for up to 200 seconds of additional fuel burn in each race.

Full build notes:

iRACING: (8.39.0)

————————————————————–

General

All tables displayed throughout iRacing have been updated so that they always show the most important and relevant information regardless of the iRacing window width.

– – This means the most important information for all tables will remain, even if the iRacing window is extremely narrow. Also, as window width increases, a logical priority of additional columns will be added to the user’s view while maintaining optimal legibility and column width.

– – This also means some items are no longer visible at some breakpoints. Typically this information is available by either making the UI wider, decreasing the scale, or clicking on a row to open the relevant menu.

Logic added to prevent the Updater from being launched more than once, even if Update is clicked multiple times.

– – This should prevent users from getting into a state where they need to manually execute the iRacingUpdater.tmp.exe in order to complete the update process.

Fixed an issue that could cause iRacing to fail to load when freshly installed and using a screen resolution of 1920×1080 or smaller.

Fixed an issue that could cause iRacing to fail to refresh when Maintenance mode ended.

Results

An event log table is now available on the Results screen.

– – It appears below the Results table and displays the lap number, time, and event description. It also includes checkboxes that highlight the associated rows in the table when selected.

– – There is another update coming to improve the behavior of the “Highlight By Event” selection to allow it to work for big, some might say “Special”, events.

Paint Shop

Fixed an issue with rendering cars.

SIMULATION:

————————————————————–

Race Control

Fixed an issue where some Drive Through Penalties were behaving like Stop-and-Go Penalties.

Fixed an issue that could allow the “Ready to Race” button to appear when a registered driver was already in the final Session of an event, and there were no additional Sessions for which to be ready.

Graphics

Fixed an issue that could cause older track surfaces to appear extra shiny.

Fixed an issue where car paints could shuffle onto incorrect cars when a Session’s video memory requirements greatly exceeded the GPU’s dedicated RAM. For example, when running a very large session on an older GPU. In this case, texture quality needed to be reduced to fit the Session into video memory, and that was interfering with the Simulation’s car paint management.

Fixed an issue where the Simulation only supported 44 paint jobs if the user’s GPU VRAM allocation was set to less than one gigabyte in the Graphics Options. So if the field was more than 44 cars and the GPU was older, some of the cars would remain unpainted.

Fixed an issue where if a car in a Session had an invalid paint scheme or invalid paint files, it could cause other cars to appear untextured or white.

Fixed an issue where if there was a car visible in the world, but the previous driver had exited the car, the car would not repaint until a driver got back into the car.

Audio

The selection order for the Driver Audio Filters have been reorganized in order of intensity.

Fixed an issue that was causing extra static sounds in the Spotter/Crew Chief and Voice Chat channels.

Spotter – Crew Chief

Requested damage report calls will now be received regardless of the chattiness level.

Spotter – Foreign Language

The Russian Dmitry Eniseev spotter pack has been updated.

– – Spasibo, Dmitry!
