This Patch release aims to fix some of the issues seen with the 2016 Season 3 Release. We hope this improves your racing experience!
CHANGE LOG:
Simulator
– Fixed an issue that could have caused an unnecessary request to run the Microsoft C++ runtime installer for either x86 or x64, even if the required files were already installed.
Race Sessions
– Fixed an issue seen in the Blancpain Endurance Series where sessions were being split into larger run-groups than dictated by the track.
Dynamic Track
– For sessions using an Automatically Generated track state, the default starting usage will now vary by a percentage based on the following:
– – Session Type = Such that earlier sessions, such as Practice, are cleaner than later sessions, such as Qualifying. This behavior was originally done and this behavior continues with this update.
– – Time of Day = Such that sessions earlier in the day are cleaner than session later in the day, reflecting usual track usage throughout a given day.
– – Weather = Such that the cloud cover affects the likelihood that relatively recent rain may have compromised track time and/or washed away some percentage of the previous track state. Also, for sessions with Realistic Weather, a random factor is also used to account for variation in track usage due to miscellaneous events prior to the session.
DirectX 11
– Fixed an issue with missing external car shadow volumes.
– Fixed an issue where the framerate could drop dramatically due to particle effects at night tracks.
Macros
– Fixed a bug with pit macros that stopped you from unchecking two tires at the same time, (ie: #-rf -rr$).
Telemetry
– Session string is now updated as soon as the sim starts to avoid leaving a stale string around from a previous session.
Oculus Rift
– Virtual mirror can now be enabled for use with DirectX 11.
– Fixed the text cursor in Edit Widgets.
Peripherals
– The “forcemap.csv” file will now attempt to load from the root iRacing folder if not found in a custom controls folder.
