iRacing 2024 Season 1 Patch 2 Improves Newly Released Track Performance

Before the holidays iRacing released a second patch, attempting to fix the performance issues users have reported on their newer track releases.

Historically iRacing tracks have had very limited detail away from the racing surface (outside the walls/barriers), so it’s not surprising really to see an uptick in specification needs as they have attempted to improve this. I’d be very interested to know whether any of the recent performance tweaks have come from reversing previous graphical enhancements.

Build notes:

iRACING:

————————————————————–

Cart

Improved the flow when a user attempts to register for a session where they do not own any of the necessary content used in the session.

Hosted Races

Resolved an issue when clicking on the “See Full Profile” button of the session host was opening the Session Info modal rather than the user’s Profile.

Car & Track Info

Resolved an issue when registering for a multiclass hosted session from the “Find Session” tab of the Car or Track modal was not finding the session to which the user was registering.

Results & Stats

This update fixes the images in the logo column of the Series Stats & Standings table.

Series List

Fixed “Full Series Page” button alignment in Race Guide view.

SIMULATION:

————————————————————–

Graphics

A sweeping change has been made to the processing of tree textures. SpeedTree textures have been added to the texture tossing algorithm. Whenever the application is running with low video memory, the SpeedTree textures are now downgraded in addition to other objects. This should improve the framerate for users with lower video memory.

– – The SpeedTree system is used at all of our new tracks.

For SSR, fixed a Simulation crash issue that could occur when enabling SSR on Low, after loading into a Session with SSR disabled (and while also having SSAO enabled).

Audio

Sounds for sawtooth and rumble strips as well as rumble curbs have been improved.
