Rainbow Six Siege Patch 1.2 Released

Today Ubisoft are sharing their second title update. Keep in mind that they will be improving with every update. The changes described below will take effect on January 7th 2016.

Please refer to our post about our January 2016 Priority – Fixing Top Issues to see our current plans and steps we are taking to improve the game. Note that this patch, Update 1.2, will not fix all of our current top issues and that we are actively working on fixing them as soon as possible.



Updated the server tick rate
With the goal of improving positioning and shooting replication, we had deployed a first update in which the player position update rate is set to 60 times per second (vs. the previous 30). This change however has been done in an intermittent fashion and in certain regions only, as we were testing various configurations. We are now satisfied with its state so we are now deploying this update to all users.

Data center selection is now possible
To change their default data centers, users can select their Rainbow Six Game file (usually located in C:\Users\your name\Documents\My Games\Rainbow Six – Siege\your Uplay ID), to select GameSettings.ini. Once opened, in the data center section, replace the word ‘default’ by the region’s short name that you wish to have as your default data center. Then, save the file. The next time you launch the game, your default data center will be the one you have selected.


Refining the quality of PVP matches with more evenly matched opponents

  • Added a criteria that increases the odds of pre-made parties being matched against a squad with an equal number of pre-made parties within them.
  • Skill criterion originating from the player’s region is now more precise.

Improved connectivity to PVP and PVE matches

  • Increased match quality by ensuring players using the same data center get matched together, leading to better ping.
  • Improved accuracy of the estimated waiting time while in lobby.


Please be aware that this is not an exhaustive list and that we are only highlighting fixes that were done about the most commonly raised community bugs.


  • Ranked matches HUD synch with Casual update has been applied (read: playlist changes from this forum post).

Gaming since the Atari 2600, I enjoy the weirdness in games counting Densha De Go and RC De Go as my favourite titles of all time. I prefer gaming of old where buying games from a shop was a thing, Being social in person was a thing. Join me as I attempt to adapt to this new digital age!
