If you're going to make a post, at least put some effort into it. Version 3.9.4 – April 23rd, 2026 GSX Pro NEW: VR-friendly menu. A new pinned-menu mode (Disabled / Enabled / Auto-VR) keeps the panel on screen as a compact status view after menus close, recallable via hotkey without reopening from the toolbar; in VR the X icon minimizes to that status view instead of duplicating the toolbar close. Options that would open a desktop dialog (airport map, editors, settings) are greyed out with a VR-headset icon and ignore clicks. Also useful to non-VR users — especially in multi-monitor setups, where the pinned status view can live permanently on a side display. GSX Pro NEW: Live status page. After a menu timeout or a user choice — the moments when the panel used to close automatically — the pinned menu now stays visible showing current aircraft, airport + parking (with any non-default gate customization), SimBrief status, and one line per active service with per-vehicle phase, ETA, fuel progress and bill, operator name, and "waiting for…" blockers when a service is stalled on another. GSX (all versions) NEW: Defueling support. Picking a refueling preset below current fuel (or a SimBrief plan lower than current) auto-switches the Fuel service to defueling — the truck pumps fuel out progressively and charges a per-gallon "Defuel fee" service charge (the returned fuel isn't reused). Works for both the standard Servicing and the custom-panel (EFB / MCDU-driven) flows. Preset entries whose target is below current fuel are tagged with [DEFUEL] in the menu so the direction is obvious before picking. GSX (all versions) NEW: Adaptive refuel presets. The 7-preset ladder shown by standard Servicing now adapts to the aircraft's total fuel capacity — GA, Regional, Narrowbody, Widebody, and Ultra-Long-Haul tiers — using the sim's own fuel density so Jet-A, 100LL, and other fuel types all tier correctly. Aircraft handler scripts can override with an airframe-specific ladder via a new fuelPresets() method; see the Handler Scripts Developer Guide. Only applies to aircraft using the default SimConnect fuel system — aircraft that drive refueling through their own EFB / MCDU take the custom-panel flow and never see the preset menu. GSX Pro NEW: Menu graphic overhaul. Hotkey rendered as inline keycaps, menu-option numbers as smaller keycaps, two-line titles supported; per-service icons and color-coded status (grey / green / yellow) on the status page; startup progress bars redesigned with smooth animation. GSX Pro NEW: GSX hotkey can now be rebound directly from the new status page — double-click the keycaps in the "GSX Menu" button, press the new combo, 2-second grace to confirm or re-press. The new hotkey is saved to hotkey.json and survives panel reloads and Couatl restarts. GSX (all versions) NEW: Push-in to Park now supports "exclusive" parking stands (scenery-authored tail-in BGL), in addition to the dual mode shipped in 3.9.2. The tug spawns on the correct side from the aircraft heading at the taxiway entry, and pull-out from a tail-in parked aircraft works along the same stored route. GSX (all versions) NEW: "Warp to point" on the airport map. Click any empty area of the Airport Viewer to drop a draggable / rotatable airplane cursor that edge-snaps to the nearest taxiway or runway; the Warp button teleports the aircraft to that position and heading. GSX (all versions) NEW: Handler scripts: setVdgsUnits / getVdgsUnits closures let aircraft and airport handlers override the VDGS / marshaller unit of measure (metric / imperial / sim default). Airport overrides win over aircraft overrides. GSX (all versions) NEW: Handler scripts: aircraft.idMajor and aircraft.idMinor exposed on the aircraft proxy for numeric-id filtering, as an alternative to ICAO string matching. GSX (all versions) NEW: New per-vehicle state LVars for 3rd-party integration, one per dispatched vehicle (fuel truck, catering, de-ice, baggage loaders / trains, stairs, buses, pushback tug, GPU, water / lavatory). Named L:FSDT_GSX_VEHICLE_<CLASSNAME>_STATE (e.g. L:FSDT_GSX_VEHICLE_FUELTRUCK_STATE, L:FSDT_GSX_VEHICLE_PUSHBACK_STATE), each carries an integer sub-state that tells the vehicle's current phase — approaching, connecting hose, pumping, disconnecting, leaving, and so on. Complements the existing per-service state LVars by exposing what the individual vehicle is physically doing right now. Full reference available in the new GSX LVars Developer Guide. GSX Pro Change: Restart flow and background stability. Progress bars now appear during external Couatl restarts and report additional phases (AI, AI Traffic, Airport, DLCs) for a smoother climb; crash detection no longer trips across a deliberate restart. GSX (all versions) Change: MSFS Steam vs Store edition is auto-detected by UserCfg.opt modification time, fixing wrong-folder detection when both installs coexist. GSX (all versions) Change: "Reset" on a parking customization now clears every persisted field (push-in mode, MARS sub-positions, all waypoint / path-thickness properties, sibling MARS INI sections). Previously several fields survived a reset. GSX (all versions) Change: MARS proximity detection now accepts proximity to any sub-position's area, not only the parent's — parking at a substantially offset sub-position now correctly triggers GSX. GSX (all versions) Change: Engine / brakes wait prompts during towing are re-shown if the state flips from "met" back to "unmet" mid-operation, so the tug no longer silently spins with no visible prompt. GSX (all versions) Change: The "Additional Services" submenu entry now ends with a ▶ marker (or "-->" on legacy FSX / P3D), so it's obvious it opens a submenu. GSX (all versions) Fix: Map dialogs (airport viewer, pushback quick-edit, vehicle-position editor) now block input during initial load — no more Windows "disabled window" ding or permanently unresponsive dialog when clicking during the first second. GSX (all versions) Fix: Reposition menu now shows MARS sibling stands at the current parking; only the occupied sub-position is hidden. GSX (all versions) Fix: Exiting the 3D parking editor no longer crashes at stands with rearPax* waypoint configurations. GSX (all versions) Fix: Towbarless push-in now tears down completely on abort — no residual engine hum and no orphan bypass pin on the aircraft nose gear. GSX (all versions) Fix: Push-in towing now follows the route shown on the map instead of cutting straight through obstacles; the bearing filter rejecting forward-route nodes has been removed. GSX (all versions) Fix: Tow tug now re-materializes at its initial position after a completed tow instead of remaining at the gate. GSX (all versions) Fix: Warp to a push-in "exclusive" parking now places the aircraft at the stand (tail-in) instead of on the push-in entry on the taxiway. GSX (all versions) Fix: A second towing request after the first was cancelled no longer produces a one-node straight-line path (stale pending-destination tracking collapsed start and goal nodes). GSX (all versions) Fix: Engine noise emitter: idle/rev sounds no longer keep playing after a vehicle is destroyed mid-crossfade, and subsequent run()/idle() calls no longer raise AttributeError after destroy(). GSX (all versions) Fix: Fuel billing now reflects the net fuel transfer rather than absolute work moved. Aircraft EFBs that internally drain tanks to a floor and then refill to the target (e.g. the default A320 workflow) no longer double-charge — the bill covers only the actual fuel delta the customer requested. GSX (all versions) Fix: Deboarding clicked while the session is tearing down no longer crashes the service on an uninitialized baggage train.

That is the DLSS enabler mod menu. The tilda key (~) activates it. I assume you have it installed and didn’t know it or forgot? It’s an amazing mod!! FYI - turn on the Ghostbuster option and set overdrive to PERF. Works much better. https://forums.flightsimulator.com/t/dlss-enabler-multi-frame-generation-for-all-gpus-game-changer/756881/320

This is nothing new and is certainly not new to SU5. Frame gen for years with MSFS has operated this way and becomes inactive when you click off the sim. I run a 3 monitor setup and have dealt with this since day 1 of frame gen. Unless you’re doing a bunch of panning around when you click off the sim, you really won’t notice it.

So at this point I’ve completed probably a dozen or so flights including several long hauls. This mod is completely stable for me and I’d argue it has made my sim more stable. GPU utilization and temps are improved with 3x, very few visual anomalies, and consistent performance with locked fps at 117. Flying into large airports like EGLL, KLAX, KORD, KJFK shows very little dip in performance… literally a couple frames. The only thing that still takes a bit of a hit are the high level/thin clouds… for whatever reason on ultra they’re terrible, but even then my fps only dipped into the high 90s. Overall, this has been a phenomenal mod and is something I’m surprised hasn’t gained more attention. I can only speak for a 4090 and for MSFS 2024, but so many users would benefit from this mod.

Perfect - I was monitoring them during that flight and my CPU & GPU temps were perfectly normal. Honestly, it seems like my system is less stressed than it was before with lower cpu & gpu utilization since using this mod. @Wise87 said it well - it's freakin black magic haha

Just wrapped up a 10.5 hr flight from SFO-EDDF. Wanted to test the stability of a long haul. It performed amazingly! Coming into EDDF with over 30 planes on the ground while on VATSIM, running 4k and ultra/high settings and I never dropped below 110 fps. I’m locked at 117 fps.

It's a known bug. Supposedly it's fixed in the most recent SU5 beta.

Just did my first real flight with it into KEWR which I would say is a highly demanding area/scenery. I dropped down from my locked 117 fps to 115 fps for a split second. Using AutoFPS in conjunction with it made the approach absolutely amazing. Excited to do more flights with this!

Just started using this with my 4090 and in conjunction with AutoFPS. I have to say at least as of this moment I’m totally blown away. I saw Chewwy94 was using it, and @Reset XPDR recommended it as well. It was stupid easy to setup by dropping a DLL file into a folder. Made a few minor adjustments to the mod that were recommended by Chewwy (enable ghost buster and overdrive to PERF) and watched the magic happen! Departed out of KEWR with the PMDG 737 and was getting a rock solid 117 FPS. Not a single budge either - it stayed at 117 and never dipped! Not even to 116. There are the typical stutters when panning, but otherwise it’s amazing. Looking forward to a long haul to see if it’s stable enough of that. Very glad this was recommended!

Not sure if others would agree, but from my own experiences with flying a 172 in RL, I feel like setting the cruise power in the sim is always higher than what I’m doing in RL when I’m trying to lean it out. In the sim, I feel like I need a lot more power during cruise than what I should need. With that said, really looking forward to th me A2A 172!

Thanks for the reply and sorry for my delayed response. Currently doing a long haul, but still seeing some of the same behavior. Below I've attached two screenshots. You'll see in the first screenshot, AutoFPS is showing 138FPS, which I could tell it definitely wasn't because panning around wasn't totally smooth. In the second picture, I enable the developer mode and turn on FPS, and you see AutoFPS reverts back to the correct FPS. Also, it became noticeably smoother again. Not sure what's up but I appreciate all your help and this great product!

@Reset XPDR I'm loving AutoFPS but I do have a quick question. One thing I've noticed is occasionally I'll see my fps in AutoFPS showing 150+ fps at times which is incorrect since I have my fps locked at 115. I went to go turn on debug to see the in game fps and as soon as I did that, AutoFPS began reflecting the correct FPS and never went beyond the 115 cap. Any ideas why this is happening? Thanks!

God speed to my VATSIM controller friends this evening who will deal with the influx of L1011 pilots who haven't used anything other than a Garmin product.

Just loaded up in PANC and within seconds the entire plane is iced over including the windshield. Even with defrost on, can't clear the windshield.... not sure what I'm doing wrong here. Cabin is warmed up appropriately but just can't clear the windshield. Defrost is showing working on the tablet.

I'm happy to see the landing sounds that we previously had in 2020 will be fixed. It was really disappointing to see they were supposed to be fixed in this update... I've been asking for these to return for a year since it sounds so much better in 2020. Funny how the small details like this can make a difference.

Performance is better for sure. My biggest disappointment and I know this is trivial for many, but the landing sounds in the 2020 version are significantly better over the 2024 version and I was really hoping this update would cure that. In the 2020 version, after touchdown it sounds like the plane is alive. You can hear the tires over the runway surface. In 2024, they’re still missing. Here’s a great video reference: https://youtu.be/YpCb-uw63EE?t=181

I tried it. Didn't see any massive improvement, even when viewing the graph for spikes and smoothness. I don't think this is some magic bullet... maybe improves performance for some, but I think the majority of us will see minimal or no improvement.

2024 here and I have no issues. Did a flight in last night with the Fenix A319 on ultra/high settings and 4K... probably one of the better performing airports of its size for me.

This has to be something on your end... I've been flying the HJET with 2020 and 2024 and haven't had any issues with the escape button.

@Vector Studio

I personally prefer the authentic split screen, but I get it… especially since they’re not forcing all of us to go to it. Completely optional.

Was really hoping to see some weather improvements. Shame…

@Reset XPDR So I have to say. I was a huge skeptic of this app. Read so many of these pages… and I was to the point that I disagreed with friends about its functionality. Even labeled it as just another placebo app to make folks think their sim has really improved. Well, I’m here to say I was dead wrong. I have done about 20-30 flights so far and I really do see the benefits of this app. At cruise, seeing improved textures that I’ve never seen before, all while maintaining my fps. To coming in on approach and final with so few (if any!) stutters. Flying into DFW, LAX, JFK without a single hint of a stutter, all while flying in 4K has been amazing. I went from someone who swore off using these apps to now it’s apart of my daily process for setting up my sim. Thanks for this excellent add-on! Just thought I’d post this here for any others on the fence and to also say thanks!

I was interested in this as well, but agree with what others have said... if TAA is not what should be used, than it's a deal breaker for me as well. I use TAA exclusively and will not use DLSS.
