Stability & Performance

• Fixed loading of WASM systems and improved error handling (was causing infinite loading for some aircraft such as the ES30)

General Bug Fixes

• Fixed the order of the cameras in the panel camera

• Fixed flight outro scene sometimes displaying in the air

Glass Cockpits

Garmin G3000 / G5000

• Fixed an issue where the PFD flight director symbol would briefly appear in the incorrect location after toggling the flight director on.

Garmin G3X Touch

• Fixed an issue where the PFD flight director symbol would briefly appear in the incorrect location after toggling the flight director on.

UNS-1Ew SBAS-Flight Management System

• Fixed the fuel flow page using incorrect units with the modern fuel system

Flight System

NavData

• Fixed path point threshold crossing height values.

Aircraft Engines

Turbine Engines

• Added the TURB_ENG_COMMANDED_N1_OVERRIDE_ACTIVE SimVar to enable external control of commanded Ne via TURB_ENG_COMMANDED_N1. See SDK for details.

• Added an optional “delta_commanded_Ne_control” parameter to the [TURBINEENGINEDATA] section of engines.cfg. It specifies whether the first argument of “delta_commanded_Ne_table” represents the condition lever position or the mixture lever position. See SDK for details.

• Added validation of the number of arguments, argument ranges, and data values for the following commanded Ne multi-dimensional tables:

  • corrected_commanded_Ne_table

  • uncorrected_commanded_Ne_table

  • delta_commanded_Ne_table

• Refined the descriptions of the recently added “full_throttle_commanded_n1”, “corrected_commanded_ne_table”, and “delta_commanded_ne_table” parameters in the Package Analyzer (File Def) checks.

Career

General Bug Fixes

• Fixed visibility and wind information discrepancy between world map and briefing information.

Missions

Medevac

• Fixed an issue where the airport selected for rerouting was always the same

• Fixed an issue that caused the flight plan to be deleted when an IFR flight was cancelled

• Fixed the flight path gates and waypoint marker confusing behavior when switching to the new reroute flight plan

Peripherals

• Added options to enable/disable mouse acceleration for “Cockpit” and “External” cameras under Settings > General > Camera > Cockpit/External Camera

• Updated supported gamepads default airplanes presets:

  • Changed TOGGLE LANDING GEAR" to happen on release

  • Remapped “TOGGLE WATER RUDDER” to [D-pad right] after a delay

  • Unmapped “TOGGLE TAIL HOOK HANDLE”

• Updated supported gamepads default airplanes and others presets :

• Mapped “DECREASE/INCREASE PROPELLER PITCH” to [RB + Dpad Left/Right]/[R1 + Dpad Left/Right]

DevMode

General

• Added allowed buttons in Input Device Editor

• Improved debug vector shape

• The debug airport is now showing the airport archetype

Project Editor

• Fixed crash when capturing aircraft thumbnail for aircraft with incorrect static height

• Fixed incorrect size of thumbnail capture, now capture in 360x240 as required

SDK

SimConnect

• Fixed MapInputEventToClientEvent registering actions on joystick button 0 when an invalid button index was provided - now triggers a SimConnect exception

Tools

• Added new 3dsMax - Blender Bridge: A tool for transferring data between 3ds Max and Blender.

• Added possibility to enable masking of cubemap reflections on windshields inside cockpits using the Reflection(R), Roughness(G), AO(B) Texture of the windshield material in Blender and 3ds Max.

• Added possibility to attenuate screen space reflections on windhsields inside cockpits to the windhsield material in Blender and 3ds Max.

Documentation

• SimVars: a new helicopter SimVar - FREEWHEELING UNIT ENGAGED has been added to the documentation.

• The section on modular simobject merging has beeen updated with missing XML information.

Each new update attracts less and less interest. They got what they deserved.

What exactly can we look forward to in Sim Update 6? Will any of us actually notice anything different?

Probably more stability and even better overall performance.

I'm not 100% sure but since I now use only default ATC and AI Traffic I believe I find it better, more consistent that I used to when I tried it the last time along SU4, but that's a long time ago....

MSFS 2024 SU6 beta runs smooth & stable, and before whenever I activated the sim AI traffic and ATC I used to get stutters, and it was the only situation I used to get it, but now it runs OK!

Yes, my performance is better than ever. I really never had many stability issues. I glad they fixed the camera views on this latest beta release. Landing and taxing around the new Ini KORD in the PMDG 737 is so smooth with AIG traffic. Last beta build is running great for me.

Apart from no landing gear visibility with AI aircraft, and having to use Rex Atmos and a bit of minor sharpening on Reshade, the sim is looking and performing astonishingly well. 9/10

I suspect they're making changes on the backend with ATC processing... I'm not in the beta, but I'm noticing ATC has been better lately with descents in career missions. Sometimes ATC will ask me to descend twice, a bug that I never noticed in the past. There seems to be tweaking going on with both career missions and ATC that never makes it to the change logs.
