This is the defining characteristic of the iFly 737. FSX is an old, CPU-bound engine. Many complex add-ons (like the PMDG 747 or MD-11) could bring FSX to a slideshow on older computers. The iFly 737 is highly optimized. Users report significantly higher Frames Per Second (FPS) compared to the competitor PMDG 737NGX. For simmers running FSX on older hardware or laptops, the iFly is often the only viable "heavy" jet option.

Historically, the iFly 737 has been priced lower than its main competitor. Combined with the included 737-800, -700, -600, and -900 variants, it offers immense value for money. ifly 737 fsx hot
The iFly 737NG is widely regarded as one of the most significant "heavy jet" add-ons released for the aging FSX platform. For years, it stood as the primary competitor to the PMDG 737NGX. The iFly version is often described as the "pilot's aircraft"—offering a balance of high-fidelity systems simulation and better frame rate performance compared to its rivals, making it a "hot" item for users with mid-range hardware.
The iFly 737 is not a default aircraft upgrade; it is a study-level simulation. This is the defining characteristic of the iFly 737
The "hot" moniker also applies to the livery community. Because the iFly uses a standard texture mapping (similar to the default 737 but higher resolution), repainters love it. You can find virtually any airline:
Must-have mods to make it "Hot":
Unlike some add-ons that require complex configuration files or have prone-to-crash gauges, the iFly installer is straightforward. It is known for being stable over long-haul flights, rarely crashing the simulator due to memory management issues (VAS).
