Microsoft Releases Sim Update 5.1 for MSFS 2024
Quick summary· AI-generated
Sim Update 5.1 fixes memory and texture streaming issues that caused terrain quality to degrade under load, resolves an avionics electrical system bug causing intermittent display failures, adds runway lighting support to Career Mode missions, fixes firefighting mission burn effects, and improves third-party traffic add-on and PlayStation 5 compatibility. The patch also resolves WebAssembly crashes affecting aircraft like the Aerostar 600 and ATR MSFS 2024 variants.
Excerpt from Threshold
Microsoft has released a follow-up Sim Update 5.1 for MSFS 2024, which addresses a range of issues that emerged during the original Sim Update 5 launch in late April.
The patch addresses several issues related to memory usage, scenery quality degradation, avionics, Career Mode, third-party traffic, and PlayStation 5 compatibility.
Memory and Scenery degradation
First and foremost, texture mip streaming under heavy memory load has been improved, and terrain quality degradation when memory runs low should be less noticeable.
Several crashes have also been fixed, and work has been done to reduce memory usage.
Avionics & Displays
An electrical system issue could intermittently cause avionics and system components to erroneously report a circuit loss of power, resulting in displays rebooting or failing to function. This is now fixed with Sim Update 5.1.
Career Mode Runway lighting & Fire Fighting
Runway lighting systems are now taken into account when using Career Mode, so that missions can begin or end at night, provided the fields you are flying to have suitable lighting.
Asobo has also fixed the burnt-ground effect that was previously present during firefighting missions, and PlayStation 5 players should now be able to fly heavy cargo missions again.
Third-party traffic pushback
Some smaller fixes related to third-party traffic add-ons and pushback have been implemented, along with additional PS5 compatibility improvements and SDK updates.
Crash fixes
WebAssembly memory allocation issues that could cause crashes with the Aerostar 600, as well as a fault affecting modules built with SDK version 1.6.9, have been resolved.
The latter was responsible for crashes with the MSFS 2024 version of the ATR.
Sim Update 5.1 Release Notes
Stability & Performance
Improved handling of texture mip streaming quality during high memory pressure conditions.
Improved terrain degradation when memory is getting low.
Fixed various crashes and improved memory usage.
Glass Cockpits
Fixed an issue with the electrical system that caused some avionics & systems to think that a circuit had been powered off periodically causing some reboots and loss of function.
Career
Mission availability times now take runway lighting systems at both the departure and arrival airports into account, allowing missions to start or end at night when adequate lighting is available.
General Bug Fixes
Fixed burn ground effect in firefighting missions.
On PlayStation 5, fixed an…
