The key takeaways from this new update are improvements to boot times and download speeds. In Update 12 optimizations for the “checking for update” phase have been added. These optimizations improve the booting times for the game as well as download speeds within the installation manager.
If turbulence is a big deal for you the patch has added the option to customize the intensity of the turbulence experienced during flight. This patch also brings the Spotlight Event Pack which brings a selection of 13 spotlight events from the past.
Optimized the “Checking for updates” phase to reduce the booting time of the simulator; improved the download speed in the installation manager; improved loading time before booting to the main menu
Added a new assistance option to customize the intensity of turbulence experienced during flight (based on current altitude, environment, and weather conditions).
Turkish and Korean languages have been added to the sim
Added an input key to toggle Flight Assistant Panel
Spotlight Event Pack: a pack of activities is now available in the Marketplace, which contains a curated selection of 13 Spotlight Events from the past. Please note: completing these activities will not count towards Spotlight Event-related achievements.
General Bug Fixes
Several crashes have been fixed across the title
Fixed a bug in the purchase flow of MSFS Marketplace
Added Keyboard shortcut to toggle Screen Narrator on/off
Control Options menu stops reset to top when assigning a button.
“Set Departure”, “Set arrival” & “Zoom to Details” are now appearing when Airport Icon is clicked
Fixed aircraft visibility issues with their interior and exterior model
Corrected an issue that caused some multiplayer planes to display a purple texture on their Glass cockpits.
Fixed Engine Governor being incorrectly labelled
Fixed game freeze during boot
Added parameter to cfg that allows to fix the legacy flight model integration of the accelerations that was causing wrong accelerations and g-force calculations in the legacy flight model. Integrated collision constraint response into the force calculation for g force estimation when on ground. This allows to have 1.0 when still on ground even with some suspension systems that don’t have enough force to counter gravity.
Fixed issues in the building generation that could caused crashes
Various localization improvements
Menu
Fixed airport considered as water if runways have undefined surface type
Added Weight & Balance visualization for rotorcraft.
Navigation/Traffic
[Partially Fixed] Glass cockpit externalization has been reworked. There’s no intermediate window anymore; each glass cockpit opens a distinct window with the glass cockpit name. Window position and size is saved when ending a flight.
With multi-layout screens cockpits, mouse collision for glass cockpit externalization is now received only by the current active glass cockpit.
Navlog timer no longer resets when user closes and reopens it
Fixed SimConnect injected traffic planes not following the assigned flight plan
Fixed live traffic planes incorrectly following departure procedures
Also fixed live traffic planes staying stuck at hold short in some airports
Fixed live traffic planes staying at low altitude after takeoff
Fixed SimConnect injected traffic being often unable to depart from the departure gate
Also fixed traffic planes causing performance issue in the world map
Fixed live traffic planes sometimes not showing nameplate
Fixed live traffic planes sometimes spawning at an incorrect location and unable to move
Also fixed live traffic planes staying at low altitude during go around
Fixed a crash where ATC uses an invalid runway number
Glass cockpit: Waypoint with no associated city now show an empty city field instead of random characters.
Glass cockpit: NavigationData expiration year is now properly displayed when date range extends over two years.
Weather
[Partially Fixed] Heat only thermals are limited in height up to the cloud base (except under clouds)
Limited and tuned negative thermals around clouds and hot ground.
Reduced thermals close to ground.
[Partially Fixed] Improved thermal slanting and cloud alignment.
Reduced “blue” hot ground thermals in rain, with altitude and with high winds
Reduced mountain turbulence with altitude
Maximum vertical wind speed in storm clouds / TCU has been increased
Fixed a cloud popping issue when updating Live Weather data
Fixed a problem where in water presets, water would be iced for the physics but displayed as water in the rendering.
General Live Weather improvements
Live Weather now uses server time instead of local time to avoid inconsistent or no live weather
Date of METAR files is now checked before ingesting the data to avoid replacing current METARs with out-of-date METARs in case of CDN issues; this also reduces bandwidth usage
Fixed an issue that would potentially stop the game from retrieving clouds
Fixed an issue where incorrect weather was injected while retrieving new data, potentially causing abrupt wind and pressure changes as well as cloud popping
Also fixed a Rendering issue where clouds were ghosting into the sky at horizon
Activity
Fixed various issues on leg start in bushtrips (#1)
Training activities are now recorded in logbook
Fixed an issue that caused the P-51 to run out of fuel too early in Reno races
Fixed an issue that could cause the engines to shut down when first starting a mission.
In Bushtrips, the Description Box displays incorrect values for the Flight Length, Flight Duration, and Number of Legs
