https://forums.flightsimulator.com/t/sim-update-3-beta-1-5-3-0-release-notes-may-23rd-2025/722678

 

Stability & Performance

• Fixed a somewhat rare crash occurrence of the model behavior parser due to recent changes making it run in parallel (was introduced in SU3)

• Fixed wrong usage of resized bitmap dimensions instead of original ones when sampling textures (fixes WASM gauges corruption on Xbox Series S and on PC with “Low” texture resolution)

• Fixed random live view leak for WASM instruments (could impact VRAM after multiple restarts)

General Bug Fixes

• Fixed an issue where the selection cursor could disappear in the marketplace tab in the aircraft selector

• Fixed planes flares occlusion when using multiple windows.

• Fixed an issue causing incorrect occlusion of plane flares near screen edges.

• Resolved an artifact regression issue involving trees and fog rendering.

Aircraft

• Corrected the contact points to 0 to fix the aircraft (B737, DA-62, Extra330 and Hot air Balloon) sliding sideways during belly landing.

• Fixed incorrect wind calculation at the top of certain buildings and object structures that could happen in the Needles landing challenge and other places.

Boeing 737 MAX 8

• Adjusted the sensitivity of the trim wheel.

Heart Aerospace ES-30

• Fixed wipers disapear depending of the cockpit camera rotation

Physics

• Fixed fallback behavior when “empty_inertia_tensor” is invalid: now correctly reverts to legacy logic even if legacy parameters (“empty_weight_pitch_MOI”, “empty_weight_yaw_MOI”, “empty_weight_roll_MOI”, “empty_weight_coupled_MOI”) are missing.

Flight System

Flight planning

• Fixed multiple issues related to flightplan sync between EFB, GPS, ATC and ribbons.

EFB

• Polished the panel border stylesheet

Traffic

Air Traffic

• Parked aircraft now have a better mix of planes and liveries.

• Fix remaining cases where unoptimized models would be used for AI Traffic.

• Adjust ratio of parked aircraft to be spawned and fix issues that can lead to overcrowded airports.

• Fixed a problem where parked aircraft had a chance to not fully load the model and stay invisible.

DevMode

Camera Editor

• Fixed a crash when opening the Camera Editor from the Mission Editor

SimObject Editor

• Fixed several incorrect behaviours when using the Edit in place mode

SDK

Exporter 3DSMAX

• Fixed exportnormal scale

• Fixed bug when creating preset group in new scene

• Properly initialize Default option preset (fix double add glitch)

• Visual differenciation between model groups and gltfs in lists

Just tried a flight with the Fenix in the new version. GSX not working. Opened the MSFS EFB to look at a chart and CTD. Rolling back to SU2.

Not on mine - but I don't have it in default location.

Happens to me too in SU2. To make the menu appear, once the plane is loaded go to your start menu and type "GSX" in the search. There should be a result named "Start Couatl for GSX MSFS". Click on that and wait like 5 or 10 seconds. After that the GSX menu in the sim works as intended.

My observations so far:

The bug with controllers disconnecting is fixed, the bug with artifacts on trees when there is fog is fixed, the bug with the drone view going to the other side of the world if we use a key to activate it and causing a crash is still not fixed.

the halo effect? or something else?

No, it wasn't the halo, it was more like a flickering on trees that only happened when there is fog or mist and was introduced with the 1.5.2.0 version.

I made a clean install for this new su3 beta, empty community folder, located outside of the default Path just as the full Packages folder and subfolders.

Going to test with default stuff ONLY, including AI Traffic and ATC.

Will try to resist installing Fênix and a few more addons for as longas I can.

[vonduck]

Be keen to see the results of that test @jcomm!
