========================================================================


This Patch includes a variety of updates and fixes for the 2023 Season 3 Release.


[h2]iRACING:
[/h2]--------------------------------------------------------------
General
Fixed an issue where the iRacing window would appear to load, but could not be found anywhere on the screen.

Paint Shop
A new sponsor has been added to the Paint Shop, Screen to Speed!


[h2]SIMULATION:
[/h2]--------------------------------------------------------------
Steam Users
The Store purchase prices for both Cars and Tracks for iRacing Members with accounts through Steam have been raised by up to $1.00 each. iRacing Members that subscribe through iRacing directly have no change to pricing for all Cars and Tracks.
- - While direct iRacing purchases add the End-User Vat/Taxes to the price before completing the purchase, currently for Steam members, the End-User Vat/Taxes are built into the Steam price and purchase system. Therefore, some direct iRacing customers may have been paying more than some Steam customers. Because of this, Steam content pricing has increased by up to $1.00 to bring the content prices closer to identical for all Steam/iRacing customers.
- - Content pricing changes are as follows for iRacing Members with accounts through Steam:
- - - - $14.95 content is now $15.95 content.
- - - - $11.95 content is now $12.95 content.
- - - - $4.95 content is now $5.25 content.
- - - - $2.95 content is now $3.25 content.
This update is in effect as of today’s 2023 Season 3 Patch 3 deployment, July 13th, 2023.
This pricing change was announced on the iRacing Forums here:
- - https://forums.iracing.com/discussion/44791/steam-content-pricing-update#latest

Connectivity
The use of IPv6 "Unique Local" addresses is now allowed.
- - Such addresses are intended to be used only inside private networks (see RFC-4193), similar to the IPv4 private address space.

Optimization
For users with hybrid CPUs, the worker thread pool algorithm will now be restricted to a maximum number of four Enki threads at any time.
- - Based on our testing and helpful feedback from our Members, this appears to be an optimal setting while we continue to investigate and test for additional hybrid CPU solutions.

Race Control
Race Admin commands are now fully disabled during Time Attack and Time Trial Sessions.

AI Racing
AI Drivers have improved their racecraft at roval-type tracks and should no longer attempt passes on the aprons of oval corners
AI Drivers have improved their skills at Mid-Ohio Sports Car Course - Full Course.

Dirt Racing
For Dirt Road racing, tire sinkage has been adjusted slightly to increase grip.
The starting state for track dirt is more varied than before, providing a slightly different experience each time you run the same track.

New Damage Model
Object parameters for cone objects have been updated. Cones should be stiffer, and slightly less likely to get lodged inside other objects and cars.

Graphics
Fixed an issue where SpeedTrees appeared extra dark at night.
Fixed a crash-to-desktop error that could occur when switching to SPS when FSR was enabled.
Fixed an issue where headlights were super effective at illuminating SpeedTrees regardless of distance.

Virtual Reality
Fixed an issue with the appearance of low resolution particles while AMD FSR was enabled.

===========================================

This Patch includes a variety of updates and fixes for the 2023 Season 3 Release.


[h2]iRACING:[/h2]
--------------------------------------------------------------
Hosted Sessions
Hosted sessions using Fixed setups now display the setup names in the Session Info tab of the modal.


[h2]SIMULATION:[/h2]
--------------------------------------------------------------
Optimization
Improved the Enki worker thread pool allocation algorithm.
- - This allocation adjustment should greatly improve performance for Enki threads on Intel 12th Gen CPUs.

Options
Helpful text has been added to the voice chat notification dropdown menu.

Dirt Racing
For the Dirt Refresh Project, reduced the variance in the amount of water in the track on dirt road courses.
For the Dirt Refresh Project, dirt displacement from tires on dirt road tracks has been reduced slightly.

AI Racing
AI Drivers now classify cars in lower classes more as obstacles rather than other drivers, which should allow for much more decisive passing. They are also hard-coded to think slower drivers are pathetic, so up your game!
AI Drivers have improved their passing techniques for cars at very different speeds. They should move laterally to pass at a more optimal distance from the target.
Further improved AI Drivers’ lateral positioning alongside other cars while racing on Road tracks.

Spotter
The spotter message for setting the overall fastest lap will now only play for Open Practice or Race Sessions. In lone sessions, the personal best message may play instead.

Graphics
Fixed an issue in Windows 11 where VSYNC could not be disabled when running the Sim in a window. This also fixes an issue in Windows 11 where the graphics auto-config always detected high-end GPUs as low-end GPUs, due to the test getting locked to the refresh rate and messing it up. This change also allows VSYNC to be toggled for windowed modes for the first time, and also now VSYNC setting changes take effect immediately without restarting the sim.
- - NOTE #1: there are cases due to Windows and device drivers where VSYNC settings don't work still, where VSYNC won't turn on. For instance, usually it doesn't work if running using NVIDIA Surround, etc.. Also device driver settings may be overriding the Sim's application settings.
- - NOTE #2: When launching in full-screen mode with VSYNC off, if you Alt+Enter or Alt+Tab out of full-screen into a windowed mode, VSYNC will usually automatically enable until you Alt+Enter back into full-screen. It seems to be a DXGI limitation.

Force Feedback
Fixed an issue that could cause the wheel force slider in the Options tab to fail to auto-detect your wheel if you had not yet entered a car.
Some additional wheel models have been added to the force feedback auto-detect routine.


[h2]CARS:[/h2]
--------------------------------------------------------------

For the New Damage Model, fixed an issue where heavy damage to only body panels could erroneously cause a Meatball flag.

Cadillac V-Series.R GTP
For the New Damage Model, aerodynamic model penalties have been updated.
For the New Damage Model, fixed an issue where heavy damage to only body panels could erroneously cause a Meatball flag.

For the New Damage Model, strengthened the rear wing and rear body panels.
For the New Damage Model, fixed an issue where heavy damage to only body panels could erroneously cause a Meatball flag.

Dirt Late Model
(ALL) - For the New Damage Model, a tuning update has been completed which increased friction on the right side-panels and tire sidewalls, stiffened the right rear corner, and lowered the break limit on the front wheels to make wall riding more dangerous.

Ferrari 488 GT3 Evo 2020
Fixed an issue where suffering critical damage to only a very small area of the car could cause an unauthorized moon launch.

Ligier JS P320
Downshifting has been made smoother, especially 3rd to 2nd gear.

Lucas Oil Off Road Pro 2 Lite
Center of Gravity height has been adjusted slightly.

Lucas Oil Off Road Pro Trucks

===========================================


This Patch includes a variety of updates and fixes for the 2023 Season 3 Release.


SIMULATION:
--------------------------------------------------------------
Security
In the Season 3 release on June 6th, 2023, changes were rolled out to improve the security of the iRacing update processing. We would like to thank Stephen Shkardoon (ss23) for the responsible disclosure of the reported issues.
- - As a reminder, security issues can be reported at [email protected].

Optimization
For the newly added Enki loading optimizations for 2023 Season 3, we have reports of stuttering from users with 12th and 13th generation Intel CPUs as well as AMD 7900X3D and 7950X3D. This Patch limits the maximum number of allowable Enki worker threads for iRacing to use to 10.
- - With our internal testing, this seemed to alleviate the stuttering issues, and no other negative impacts were found for any other users.
- - This update also allows users to manually adjust the maximum number of allowable Enki worker threads for iRacing to use. To do this, create a new entry in the “core.ini” file, “[Task] max_num_default_worker_threads=10”. Adjusting this value will control the maximum number of Enki worker threads iRacing is allowed to use for the default thread pool.
- - - - We would like to hear from you with regards to this issue! If you have a system that utilizes Enki worker threads, please let us know how these changes work for your system, and how changing your maximum allowable Enki worker threads changes your performance.

AI Racing
AI Drivers have improved their braking techniques.
Fixed an issue where the BMW M Hybrid V8 and Cadillac V-Series.R GTP AI Drivers would fail to load into Sessions.

Graphics
The way in which we check for GPU memory has been updated. This impacts how the Graphics Auto-Config sets the memory slider for users.
- - Now, the iRacing Auto-Config tool should set your memory sliders to about 80% of available memory.
Fixed an issue where some car tires did not have ambient occlusion working correctly.

Replays
Fixed an issue that could cause the Simulator to crash while watching Replays with AI Drivers. AI Drivers are less shy now.

Controllers
The shift light behavior for Thrustmaster T128 and T248 devices has been updated to better match that of other wheels.
The amount of time we suppress data collection for the Force Feedback (FFB) Auto Button has been reduced when an incident is detected. This may help the Auto Button work more consistently at some tracks.
The Force Feedback (FFB) Auto Button will now continue to collect data when driving under Caution or on the pace lap.
