Compare the best Microsoft Flight Simulator alternatives and learn when to choose X-Plane 12, Prepar3D, DCS World, FlightGear or Aerofly FS 4.
The best all-purpose alternative to Microsoft Flight Simulator is X-Plane 12, particularly for flight dynamics, aircraft development and macOS or Linux support. Choose Prepar3D for established training workflows, DCS World for combat, FlightGear for free open-source flying, and Aerofly FS 4 for smooth VR performance and quick setup.
Best Microsoft Flight Simulator alternatives at a glance
For most desktop simmers, the right choice depends less on graphics and more on the aircraft, operating system and type of flying they intend to use.
| Simulator | Best for | Main strength | Main compromise |
|---|---|---|---|
| X-Plane 12 | General aviation and airliners | Flight-model focus, global civilian flying and Windows, macOS and Linux support | World scenery is less convincing out of the box than MSFS |
| Prepar3D | Training and established P3D installations | Scenario-based operation, deep configuration and an extensive legacy ecosystem | Windows-only; licensing and add-on compatibility need careful checking |
| DCS World | Modern military aviation | Detailed combat aircraft, weapons, damage and mission planning | Regional maps rather than a global civilian world |
| FlightGear | Free and open-source simulation | No purchase required, cross-platform support and extensive configurability | Aircraft, scenery and cockpit quality vary markedly |
| Aerofly FS 4 | VR, fast loading and uncomplicated flying | Efficient performance and approachable default aircraft | Smaller aircraft, scenery and add-on ecosystem |
Which simulator is closest to Microsoft Flight Simulator?
X-Plane 12 is the closest complete alternative because it supports worldwide civilian flying, IFR procedures, general aviation, airliners, weather and third-party aircraft. It is the most sensible first choice for somebody leaving MSFS but still wanting one simulator for several types of flying.
X-Plane calculates aerodynamic forces across the aircraft model rather than relying only on fixed performance tables. That does not make every X-Plane aircraft automatically more realistic: the quality of the aircraft model, systems and data still matters. Its engineering tools and predictable simulation environment are major reasons it remains popular with aircraft developers and serious home cockpit users.
Microsoft Flight Simulator retains the advantage in out-of-the-box ground imagery, visual exploration and integrated world presentation. Our detailed comparison of X-Plane 12 and MSFS 2024 covers the practical differences in flight modelling, scenery, weather, aircraft and hardware support.
Before buying, use the X-Plane demo for Windows, Mac and Linux to check performance, controller detection and cockpit readability. A simulator that runs well at altitude may still struggle around detailed airports, in clouds or with a complex airliner.
When is Prepar3D the better alternative?
Prepar3D makes the most sense when an organisation or experienced user already has a P3D-based training setup, compatible hardware or a required aircraft package. Its Microsoft ESP and FSX lineage also makes it familiar to simmers accustomed to traditional flight-simulator configuration and scenario design.
It is not usually our first recommendation for a new casual installation. Prepar3D licence terms should match the intended use, and add-ons built for one major version may not work in another. Never assume that an old FSX or P3D aircraft will install correctly simply because the folder structure looks familiar.
For civilian desktop flying, the real decision is usually X-Plane's broad cross-platform ecosystem against Prepar3D's established training and legacy workflows. Aircraft availability can settle that choice: check that the exact airliner, avionics package or training model you need supports the simulator version you plan to install.
What should combat pilots choose instead of MSFS?
DCS World is the strongest Microsoft Flight Simulator alternative for modern combat aviation. Its focus is aircraft systems, sensors, weapons, damage, tactical missions and multiplayer operations rather than worldwide sightseeing or airline flying.
The base simulator provides a limited way to begin, but many high-detail aircraft and additional theatres are separate modules. Module complexity varies, so distinguish between simplified aircraft and full-fidelity cockpits before committing. Map and aircraft requirements can also consume substantial storage.
DCS is not a direct replacement if the goal is global general aviation, civilian ATC or long-haul airline operations. If combat is the priority, our explanation of how Steam and standalone DCS installations differ covers an important choice to make before building a module library.
What is the best free alternative to Microsoft Flight Simulator?
FlightGear is the best fully free, open-source alternative for civilian flight simulation. It runs on the main desktop operating systems and supports everything from basic general aviation to experimental aircraft and technical simulator projects.
The trade-off is consistency. One FlightGear aircraft may have a detailed cockpit and credible systems while another is comparatively basic. Scenery coverage, interface polish and documentation can also vary, so judge individual aircraft rather than treating the entire library as one quality level.
Our assessment of FlightGear's strengths and limitations explains who will enjoy it and where its open-source nature requires more patience.
Is Aerofly FS 4 better for VR or a modest PC?
Aerofly FS 4 is a strong option when fluid performance, short loading times and straightforward VR flying matter more than a huge add-on catalogue. Its default experience is easier to approach than simulators that require extensive scenery management or community plugins.
Do not treat efficient performance as a guarantee that every low-spec computer or VR headset will run it well. Resolution, headset refresh rate, detailed scenery and graphics settings still affect frame rate. It is also a weaker choice when a specific study-level airliner, worldwide scenery package or specialist hardware integration is mandatory.
Can MSFS add-ons and controls be reused?
MSFS aircraft, scenery and marketplace purchases do not transfer to another simulator. X-Plane, Prepar3D, DCS, FlightGear and Aerofly use different aircraft definitions, scenery formats, systems interfaces and plugin architectures.
Standard USB yokes, joysticks, throttles and rudder pedals are more likely to work across simulators, provided the operating system recognises them. Control profiles will still need to be rebuilt, including axis direction, dead zones, sensitivity curves and button assignments. Proprietary radio panels, switch panels and cockpit displays may require a simulator-specific driver or plugin.
A mistake we see constantly is choosing the platform first and checking the required aircraft or hardware afterwards. Verify these items before installing:
- Required aircraft: Confirm that the exact variant and avionics suite are supported, not merely the same aircraft family.
- Operating system: X-Plane and FlightGear provide the broadest desktop platform choice; Prepar3D and DCS are centred on Windows.
- Peripheral support: Check simulator-specific software for advanced panels, force feedback and home cockpit interfaces.
- Flying area: Decide whether you need a global civilian world, detailed regional scenery or a combat theatre.
- Online dependence: Consider how much of the experience must remain available when imagery, weather or account services are unavailable.
Are there equivalent MSFS alternatives on console?
There is no console alternative matching the breadth of Microsoft Flight Simulator's global civilian environment. The leading substitutes above are primarily desktop simulators, while console flight games tend to concentrate on combat or simplified aviation.
Microsoft Flight Simulator 2024 is available on PC, Xbox Series X|S, PlayStation 5 and PS5 Pro. Microsoft Flight Simulator 2020 remains limited to PC and Xbox. For a console-only simmer seeking realistic worldwide civilian flying, staying with Microsoft Flight Simulator is therefore usually the practical choice.
