Microsoft Flight Simulator Sim Update IX (v1.25.7.0) is Now Ready to Download

Sim Update IX for Microsoft Flight Simulator is here and ready to download.

Microsoft Flight Simulator’s latest Sim Update is now ready to download for PC and Xbox users. The latest sim update had a big focus on fixing pre-existing bugs and improving the general user experience.

Some of the key highlights from Sim Update IX include a new spotlight event, general stability improvements, improved popcorn cloud appearance and much more.

The release notes are pretty extensive, but there are some nice details to pick out from them. For example, it’s great to see that Azure Neural Text-to-Speech technology is now included, for more authentic sounding voices. Weather also saw improvements with ISA pressure formulas now corrected, along with a reduction in cloud banding when at close range. Various aircraft have also seen plenty of improvements, with the F/A-18 seemingly getting a lot of love from the development team. Finally, the Cessna 172 Skyhawk G1000 also saw the new CFD simulation added, which will give users the ability to take advantage of the new propeller system in the simulator.

The UI also saw some improvements. Notable changes include the ability to see the download size from the in-sim Marketplace product page, all-new filters and also panels will no longer be distorted when changing screen ratio.

You can see the full changes with Sim Update IX (v1.25.7.0) down below.
