To make the "new" iFly feel truly modern, pair it with these:
Originally developed by Flight Sim Labs (known for their Airbus A320) and iFly, the iFly 737 series was once the direct competitor to PMDG’s 737NGX. Over the years, development shifted. The "new" iteration of the iFly 737 for FSX refers to the v3.x builds (and specifically the 737 MAX add-on), which brought modern textures, improved systems, and a refreshed virtual cockpit.
Key Variants available in the "New" package:
The new version ships with a tablet-style EFB in the cockpit. From here, you can control fuel, payload, pushback, and even view navigraph charts without alt-tabbing out of FSX. ifly 737 fsx new
For nearly two decades, Microsoft Flight Simulator X (FSX) has remained a stalwart in the flight sim community. While MSFS 2020 and 2024 dominate the headlines, the "Old Guard" of FSX still boasts a massive, loyal user base. Among the most requested add-ons in that ecosystem has always been a high-fidelity Boeing 737NG. Enter the iFly 737 for FSX—specifically, the "new" iteration that has sparked endless forum debates.
But what does "iFly 737 FSX new" actually mean? Is it a brand new product, a patch, or a port from Prepar3D? In this article, we dissect the latest version of the iFly 737, its feature set, performance in 2025, and whether you should invest in this classic.
Yes—but barely. iFly has largely moved on to developing for Microsoft Flight Simulator 2020/2024. However, the support forums for the FSX version remain open. Do not expect new features (like FAULT simulation updates), but critical installer fixes that keep the activation servers alive are still maintained. To make the "new" iFly feel truly modern,
The base installer is from 2015. You need the final update.
Here is the reality check. Because the "new" iFly pushes FSX to its absolute limit, you cannot run this on a netbook.
Minimum Requirements:
Performance tip: The iFly 737 is more efficient than the PMDG NGXu (which struggles in FSX). Users report frame rates between 25-40 FPS at complex airports like FSDT KLAX or FlyTampa OMDB when settings are moderate. Turn down "Scenery Complexity" and "Water Effects" to gain 10 FPS.
The CFM56-7B engines behave correctly. You get proper spool-up times, realistic EGT margins, and the "buzz-saw" sound effect on takeoff (if you download the latest sound pack). The FADEC logic prevents overtemping, but the model still punishes you for slamming the throttles forward.
