2021 Season 1 Patch 3 - Release Notes [2021.01.13.03]

This Patch contains some updates and fixes for the 2021 Season 1 Release.

iRACING UI: (5.05.03)

Hosted Sessions

- Fixed an issue where Hosted Sessions could fail to be displayed after canceling a pending Hosted Session.

3D Car Viewer

- Fixed an issue where the iRacing UI could fail to see paint file updates in folders with more than one space in the folder name, such as the "dirtsprint winged 305" folder.

- Fixed an issue where refreshing the iRacing UI (Ctrl+R) while viewing the 3D Car Viewer could create a bad state.
- - Remember, the 3D Car Viewer should automatically update with any changes made to the paint folders; no need to refresh!

SIMULATION:

Physics

- Fixed an issue seen on some vehicles with odd hyper-extended suspension behaviors.

Race Control

- Fixed an issue that could occur where subsequent meatball black flags were not being recognized and triggered.

AI Racing

- AI Racing is now available at the following additional tracks and configurations:
- - Circuit de Spa-Francorchamps - Classic Pits
- - Circuit de Spa-Francorchamps - Endurance
- - iRacing Superspeedway
- - Richmond Raceway
- - Watkins Glen International - Classic
- - Watkins Glen International - Classic Boot

- AI Drivers have received additional training with the following vehicles:
- - Indy Pro 2000 PM-18
- - USF 2000
- - Audi RS 3 LMS
- - Kia Optima

Pace Car

- Fixed an issue where the pace car would sometimes try to move up the track very quickly on ovals once it left the pit lane, sometimes even hitting the outside wall.

Spotter

- Fixed an issue where lead-lap cars were sometimes not receive a spotter message about lucky dog or free-pass cars coming up behind them.

Pit Stop

- The speech volume of Lollipop Guy has been reduced.

Rendering

- Fixed an issue where the solar flare effect could render with a four pixel-wide defect when using 3-screen mode without actual bezels.

Visual Effects

- Fixed an issue where sparks were not elongating in the correct direction, nor where they colliding with the track surface.

- Fixed an issue where smoke puffs would move in world-space depending on the camera pitch and camera roll. This change also fixes an issue where smoke puffs would rotate with camera roll, rather than stay fixed in the world.

Audio

- Improved undertray scrapes, grass scrapes, concrete scrapes and 3D curb impact sounds.

Telemetry

- Two new tire telemetry variables have been added.
- - "PlayerTireCompound" and "PitSvTireCompound" indicate the current and pending tire compounds for the player's car respectively. Both are logged live and to disk.

Virtual Reality

- Created a work-around for a reported bug in OpenVR where the SDK returns camera frustums with the top/bottom reversed, only when using a specific SDK routine to fetch the frustums. The theory is that this is what is causing eye alignment mismatches (even with SPS disabled) on some headsets.
- - If you suspect you are having this issue, to enable the work-around, set "FixGetProjectionRawBug" to 1 inside the "[OpenVR]" section of "rendererDX11.ini" file.

This Patch contains some updates and fixes for the 2021 Season 1 Release, and the BMW M4 GT3!

iRACING UI: (5.03.01)

General

- The iRacing UI now features a "Safe Mode" for users that might be having some rendering issues with their iRacing UI.
- - The UI can enable Safe Mode for users that are having problems with the UI not rendering correctly. By default the UI will analyze the GPU settings as it starts and will automatically decide if it should start in Safe Mode. If it decides to start in Safe Mode, you will be shown an error message with further information.
- - Safe Mode fixes an issue for users without Hardware Acceleration. The issue was appearing as a large black or white rectangle instead of displaying the iRacing UI.
- - While Safe Mode is enabled, users will not be able to render content in the 3D Model Viewer.
- - - If you wish to manually override this setting, you may change the "uiSafeMode" setting under the "[Graphics DX11]" section in the "app.ini" file. Automatic (0), On (1), or Off (2).

- A Gift Card link has been added to the side-bar.

Hosted Sessions

- The logic for loading, displaying, filtering, and creating Hosted Sessions has been optimized.
- - These changes should reduce your load times and refresh rates, and increase the speed that the page updates, even during heavily populated times.

- Fixed an issue where the "Purchase" button for a Session was not changing to the "Update" button once the content was purchased.

3D Car Viewer

- Improved object positioning and camera field-of view to work better with very wide aspect ratios.

Force Feedback

- Fixed an issue where force feedback was stopping when SimRacingStudio was launched.
- - This change may also fix the issue with SteamVR stopping our FFB at launch.

BMW M4 GT3 - Prototype
