Summary (AI)

Patch 9.00 for X4: Foundations introduces significant improvements to turret accuracy and AI pilot aiming, alongside enhanced capital ship combat behaviors and weapon rebalancing. New systems for weapon heat and shield modifiers have been added, with visual upgrades to the UI and detailed equipment statistics in the ship loadout screen. Several gameplay features have been overhauled, including resource distribution for mining, missile targeting, and the addition of dedicated missile launcher slots on certain ships. The update also brings extensive fixes addressing mission issues, autopilot behavior, drone mechanics, graphics glitches, and various crashes to improve overall stability. Native support for Wayland on Linux and AMD FSR frame generation are included as well.
