FSX was released on 10 October 2006. Find its exact age, Steam Edition date, and where Acceleration and Gold fit in the FSX timeline.
Microsoft Flight Simulator X (FSX) was first released on 10 October 2006. In September 2026, the original PC simulator is 19 years old; its 20th anniversary falls on 10 October 2026. FSX: Steam Edition arrived on 18 December 2014, but it is a later release of the same FSX generation, not a new simulator.
When was Microsoft Flight Simulator X released?
10 October 2006 is the date normally used for the original FSX release and its age. Some regional retail launches occurred a few days later, which explains why another October 2006 date may appear on an old box or in a local release listing.
| FSX release | Initial release | What it represents |
|---|---|---|
| FSX Standard and Deluxe | 10 October 2006 | The original simulator and the reference point for FSX's age |
| FSX: Acceleration | October 2007 | An expansion for FSX, not a new simulator generation |
| FSX: Gold Edition | 2008 | A package combining Deluxe with Acceleration |
| FSX: Steam Edition | 18 December 2014 | A digital re-release based on the established FSX platform |
Our breakdown of the main FSX editions and packages explains what each release contains. Acceleration and Gold do not reset the underlying simulator's 2006 age.
Is FSX: Steam Edition newer than boxed FSX?
FSX: Steam Edition is newer as a product release, but not as a simulator generation. It reaches its 12th anniversary on 18 December 2026, while the FSX platform itself reaches 20 years in October 2026.
The Steam release introduced digital distribution and made compatibility and multiplayer changes, but it retained FSX's underlying 32-bit architecture. See how boxed FSX and Steam Edition differ in practice if you are deciding which age should count for your installation.
Does the X in FSX mean it was released in 2010?
No. The X is the Roman numeral for ten, referring to the title's place in the Flight Simulator series; it is not a release year. Microsoft Flight Simulator 2020 and Microsoft Flight Simulator 2024 are separate, much newer simulator generations rather than updated names for FSX.
Does FSX's age matter on a modern PC?
FSX remains usable, but its age affects performance and compatibility. It is a 32-bit application, relies heavily on single-thread processor performance, and can exhaust its available memory when complex aircraft, dense scenery and high-resolution textures are combined.
Older add-on installers may also expect boxed-edition folders, registry entries or legacy gauge components. FSX still appeals to simmers with established add-on collections or modest hardware, but anyone choosing it afresh should understand those limitations; our assessment of who should still choose FSX covers that decision in more detail.
