A new patch for Ubisoft’s latest Assassin’s Creed game will go live on PC tomorrow, having already been released for the console versions today.

1.21 will fix a handful of bugs and bring AI improvements and UI tweaks, as well as a few stability boosts. A few missions have seen fixes come in and a bug with the objectives of missions not updating has been applied, along with a fix for an issue that was having an effect on the fast travel. NPCs will now have better reaction times on ground or on vehicles, and pretty much every part of the assassin’s travel moves have had some tweak to make them function better.

If you’re curious, the full patch notes are over on the official forum thread, but here’s the stuff that was specifically a fix for the PC version of the game:

• Fixed infinite loading screen in Sequence 7.
• Fixed several geometry explosion and missing geometry issues.
• Fixed various render issues.
• Fixed several online issues.
• Minor UI improvements.
• NPC AI improved globally for reactions.
• Graphical bugs with lighting, textures and details fixed.
• Various progression problems fixed in missions.

The patch itself should be around 500MB, so the fixes will quickly be applied once you load up Steam or your game.
