Sim Update 3 Beta (1.5.3.0) Release Notes - May 23rd, 2025

RELEASE NOTES Sim Update 3 Beta - 1.5.3.0

If you are playing on PC, outdated packages in your community folder may have an unexpected impact on the title’s performance and behavior.

If you suffer from stability issues or long loading times, move your community package(s) to another folder before relaunching the title.

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
