Simulation

User Interface

• GENERAL:

  • Fixed an issue where some values had excessive decimal precision.

  • Fixed an issue where spin controls were lacking feedback when selected.

  • Fixed stutter when race flags are shown for the first time.

  • Added VR screen space controls to the Options menu.

  • Fixed a FOV calculator bug that mixed up imperial/metric units, causing the FOV to come out wrong.

  • Fixed an issue where the driver select dropdown would not update when new drivers entered the session.

  • Fixed an issue with the radar not keeping a square aspect ratio.

• DRIVE SCREEN:

  • In the F1 box, moved the real-time clock from the header space to the bottom row, and added a Sim-time clock alongside it.

  • The F2 and F3 boxes have been adjusted to no longer require a scrollbar.

  • Fixed an issue with the positioning of black box controls after moving them and then transitioning to another screen, or closing the Sim.

  • Larger size options have been added for Virtual Mirror and the Delta Bar.

  • Fixed an issue where all black boxes would grow larger when a car had a large car-specific black box.

  • The tire change feedback icon is now hidden when not in a Race Session.

  • UI layer settings for a few widgets have been adjusted to ensure layering priority for: Pit Speed, Pit Info, Pacing, Flags, and Penalties.

  • To help make the drive screen UI and text larger and more readable, we adjusted the Drive Screen to allow UI scaling past where the Session Screen will stop applying it.

Dirt Racing

• Raised the collision and damage thresholds for Dirt Road cars making contact with the environment. This allows for a bit more aggressive driving before receiving an incident from a wall or bump collision.

Graphics

• Fixed an issue where driver names that display on vehicles would incorrectly appear as uppercase, or not appear at all, when reloading the car paint via the CTRL+R command.

Audio

• Fixed some audio level and mixing issues with the updated hybrid systems for all applicable cars.

• Hybrid motor audio has been tuned.

• A setting has been added to the “app.ini” file that allows users to display sound levels in dB units or a generic slider.

  • 'soundUiControlsInDb=1' displays the level sliders in dB.

  • 'soundUiControlsInDb=0' displays the level sliders in a range from 0-100.

Controls
