When Parallel 42 announced last year that SimFX and its Immersion Packs would not be making the jump to MSFS 2024, it left a noticeable gap in the ecosystem. Those add-ons had become a staple for airliner simmers in MSFS 2020, adding the kind of atmospheric visual detail, wing condensation, engine vortices, wet runway spray, that the base simulator simply doesn’t model.
For MSFS 2024 users, that layer of visual immersion has been missing ever since.
Toronto-based TriTriSim is looking to fill that gap. The developer has announced GFX Airliner, a physics-based atmospheric effects add-on for both MSFS 2020 and 2024, with a confirmed release date of April 23.
What GFX Airliner does
TriTriSim says GFX Airliner is built around real-time computational fluid dynamics (CFD) simulations. The effects react to live atmospheric conditions including humidity, temperature, and angle of attack, and according to the developer, will only appear when conditions actually warrant them. There’s also an override available for cinematic or screenshot purposes.
The feature set is fairly broad. Wing and engine condensation trigger based on atmospheric conditions and high angles of attack. Wingtip and flap vortices appear during maneuvers and on approach. On the ground, there’s thrust reversal spray, tire kick-up, and wake effects on wet runways, along with thrust-on-rain interaction and water ingestion effects for the engines. It’s the kind of detail that tends to show up most during the phases of flight that simmers spend the most time watching, takeoff, landing, and low-altitude maneuvering.
Planned future additions include contrails and wing fade interaction with clouds.
On the performance side, TriTriSim says GFX runs entirely on C++ WASM technology outside the main simulator thread, which the developer claims means zero FPS impact. For a particle-heavy effects add-on, that’s a significant claim, and one the community will put to the test quickly.
Supported aircraft
At launch, GFX Airliner supports 12 aircraft families. On the Airbus side, that covers the A300, A320 (both Asobo and FlyByWire), the Fenix A321, A330, the iniBuilds A340 and A350, the ToLiSS A346, and the FlyByWire A380. Boeing coverage includes the PMDG 737 and PMDG 777. The MD-11 from TFDi also makes the list. It’s a solid starting lineup that covers most of the popular payware airliners currently flying in MSFS 2024, and TriTriSim has indicated general aviation support is planned for future updates.
A familiar mod, a new face
If you’ve been following TriTriSim, you’ll know them from TFX, their freeware emergency effects add-on that we covered back in July 2025. TFX brought engine fires, sparks, smoke trails, and crash animations to a wide range of aircraft in both MSFS 2020 and 2024. GFX Airliner is their first paid product, and it targets a different audience entirely: airliner simmers who want atmospheric detail during normal, everyday operations rather than dramatic failure scenarios.
GFX Airliner will launch at an introductory price of $14.99 USD, rising to $19.99 USD shortly after release.
The real question, as always with effects add-ons, is how it holds up in practice. The CFD-driven approach sounds compelling on paper, and the zero-FPS-impact claim will be one of the first things the community puts to the test. The April 23 release date is close enough that we won’t have to wait long to find out.
We’ll have more coverage once GFX Airliner is available. In the meantime, you can find more details at tritrisim.com.
