Microsoft Flight Simulator 2024’s Sim Update 5.1 lands with crash fixes and PS5 tweaks
The 1.7.35.0 patch improves memory handling, adjusts night mission availability, and fixes several problems across PC and PlayStation 5.

Microsoft Flight Simulator 2024 has received Sim Update 5.1 [1.7.35.0], and this update goes straight at a few of the rough edges players have been dealing with. The patch focuses on memory pressure, crashes, glass cockpit resets, Career mission timing, traffic add-ons, audio delay, and several PlayStation 5 fixes.
PC players should also keep an eye on the Community folder. The team said outdated packages there can affect performance and behavior, and if stability or loading times are causing trouble, those packages should be moved to another folder before relaunching the game.
