PMDG 777 vs FlightFactor 777 compared: systems, handling, visuals, performance, version traps and the right long-haul add-on for each simulator.
The PMDG 777 is the stronger all-round choice for Microsoft Flight Simulator, while the FlightFactor 777 v2 is the high-fidelity choice for X-Plane 12. They run in different simulators, so platform preference matters most. If you own both, PMDG has the edge in procedural polish; FlightFactor suits committed X-Plane users.
PMDG 777 vs FlightFactor 777 at a glance
This is a platform decision before it is an aircraft decision. The surrounding simulator affects weather, scenery, lighting, controls, performance and handling, so the aircraft cannot be compared in isolation.
| Criterion | PMDG 777 | FlightFactor 777 |
|---|---|---|
| Primary platform | Microsoft Flight Simulator generation, with separate legacy FSX and Prepar3D products | X-Plane; 777 v2 is the relevant comparison for X-Plane 12 |
| Main strength | Cohesive Boeing systems, FMC and airline workflow | X-Plane-native handling, datarefs and cockpit integration |
| Systems experience | Generally the more polished dispatch-to-shutdown package | Highly detailed, but completeness can depend on the exact v2 build |
| Manual handling | Convincing when MSFS controls and steering are calibrated correctly | Appeals to pilots who prefer X-Plane 12's flight and ground physics |
| Visual environment | Benefits from MSFS scenery, weather and lighting | Built around X-Plane 12's rendering and add-on ecosystem |
| Best for | MSFS users wanting a refined long-haul Boeing simulation | X-Plane users wanting a native high-fidelity 777 |
| Biggest buying trap | Confusing MSFS and legacy FSX/P3D editions or assuming every variant is included | Confusing the original FlightFactor 777 with the substantially newer 777 v2 |
Which 777 is more realistic?
PMDG is our pick for the more consistent full-flight procedural simulation, but FlightFactor v2 is not a lightweight alternative. Both target serious airliner operation; the difference is how completely and consistently each build reproduces the entire flight rather than how many cockpit switches can be clicked.
Realism should be judged across the FMC, VNAV, autopilot and flight director, electrical and hydraulic dependencies, fuel management, pressurisation, performance calculations and abnormal operation. PMDG generally has fewer rough edges across that complete workflow. With FlightFactor, check the implemented-feature list for the exact v2 build rather than assuming every displayed function is finished.
Do not judge either aircraft's VNAV after importing a route and immediately departing. Enter the aircraft weight, reserves, cost index, cruise level, winds and take-off performance, then resolve route discontinuities. A rejected waypoint or unexpected descent can also come from mismatched navigation-data cycles rather than faulty aircraft logic.
Manual handling is less decisive. PMDG's aircraft operates inside the MSFS flight model, while FlightFactor uses X-Plane's environment. Control sensitivity, duplicated rudder and tiller assignments, excessive dead zones and hardware noise can make either 777 feel worse than it is.
Which one should you buy?
Buy the 777 made for the simulator you already prefer unless you are prepared to change the rest of your simulation setup as well.
- Choose PMDG if MSFS is your main simulator, you value a polished airline workflow, or you want the simulator's broader scenery and weather presentation around the aircraft.
- Choose FlightFactor v2 if X-Plane 12 is your established platform, you rely on X-Plane datarefs or control profiles, or you strongly prefer its handling and replay environment.
- Choose PMDG when you own both simulators if your priority is the most cohesive overall 777 experience rather than a particular base simulator's physics.
- Choose FlightFactor when you own both if X-Plane itself is the reason you simulate: switching to MSFS solely for one aircraft rarely makes sense once scenery, controls and utilities are considered.
Aircraft variant also matters. A freighter, 777-200-series aircraft and 777-300ER do not provide identical missions or handling, and they may be sold separately. Our comparison of the available PMDG 777 variants explains which package best matches passenger, cargo and ultra-long-haul flying.
What version pitfalls should you check before buying?
Most bad purchases happen because the simmer compares reviews of different product generations or assumes compatibility from the aircraft name alone.
- Confirm the simulator. PMDG's MSFS 777 is separate from its older FSX and Prepar3D generation. FlightFactor is an X-Plane product.
- Identify the FlightFactor generation. The original FlightFactor 777 belongs to an older X-Plane generation and should not be used to judge 777 v2 graphics, systems or handling.
- Check the exact 777 variant. Never assume that one purchase includes every passenger and freighter model, engine option or expansion.
- Verify simulator-version support. MSFS 2020 compatibility does not automatically prove identical behaviour in MSFS 2024. Use our PMDG compatibility guide for MSFS 2024 before installing or purchasing.
- Update before troubleshooting. Old aircraft files mixed with a newer simulator build can cause missing displays, loading failures and unexplained system behaviour. PMDG owners can follow our Operations Center update and repair steps.
Which 777 has better performance?
There is no trustworthy universal frame-rate winner because PMDG and FlightFactor run in different rendering engines. Airport scenery, traffic, clouds, glass-cockpit refresh rates, resolution and processor limits can outweigh the aircraft itself.
For a useful comparison, load each aircraft cold and dark at a default airport, use matching weather and traffic conditions, remain in the cockpit view and wait for scenery loading to settle. Compare CPU and GPU frame time as well as average frame rate. If one test uses a detailed third-party hub and the other uses an empty default airport, the result says little about the aircraft.
Stutters immediately after loading are not necessarily an add-on fault. Shader compilation, scenery streaming, traffic injection and background utilities can all produce temporary pauses. Persistent poor performance should first be checked with third-party scenery and traffic disabled.
Our verdict
PMDG 777 wins overall for MSFS-based long-haul simulation and procedural polish. FlightFactor 777 v2 is the better answer only when X-Plane 12 is your preferred platform or its handling and integration matter more to you than PMDG's more cohesive airline workflow.
The older FlightFactor 777 should not be compared directly with the modern PMDG MSFS product. Compare PMDG with FlightFactor 777 v2, verify the precise simulator and variant, and let your preferred platform break the tie.
