iRacing 2023 Season 4 Patch 2 Adds Honda SF23 Engines

The Super Formula series now replicates the real world championship, as iRacing 2023 Season 4 Patch 2 adds Honda SF23 engines which can be chosen as an alternative Toyota power. Whether you already own the Super Formula SF23 or buy it in the future, it will include both the Honda and Toyota choices, with both using the same Dallara chassis to produce near-F1 levels of open wheel racing.

Various tweaks have also been applied to the SF23, along with the new Ferrari 296 GT3 introduced at the start of the season, and a few of the other cars also get slight changes or new setups. There are also tweaks for Zandvoort, and Kern County Raceway Park, along with slight changes at Fuji, Homestead Miami and Kansas.

And there should now be a fix for issues with liveries accidentally appearing on the wrong cars, and for some remaining unpainted with more than 44 vehicles on track, or if one driver was running and invalid paint scheme or file.

iRacing 2023 Season 4 Patch 2 Release Notes:

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.
