Ubisoft released Rainbow Six Siege update 1.000.155 (version 3.50) on September 29, 2026. This patch focuses on resolving technical performance issues for PlayStation 5 Pro users and addressing matchmaking friction within the active Wasteland Circuit mid-season event.
PS5 Pro Performance Mode Fixes
A primary focus of this update is the resolution of a specific issue affecting Performance Mode on the PlayStation 5 Pro. Following the launch of Year 11 Season 2, players on the high-end console reported inconsistencies when utilizing this mode. The 1.000.155 patch optimizes the game’s interaction with the PS5 Pro hardware to ensure the intended frame rate and stability are maintained during high-intensity firefights.
Wasteland Circuit Matchmaking Adjustments
The update also targets the user experience in the Wasteland Circuit limited-time event. Previously, players encountered a persistent matchmaking delay that occurred immediately after receiving the “Match Started” notification. This bottleneck prevented teams from loading into the event map efficiently. According to the official Ubisoft update notes, this delay has been resolved, streamlining the transition from the menu to live gameplay.
Additional Changes and General Fixes
While the PS5 Pro and event fixes are the priority, the patch includes several minor adjustments and general stability improvements for all platforms, including PlayStation 4, Xbox Series X|S, Xbox One, and PC.
- Black Ice Arsenal Bundle: This bundle has been restored to the in-game store and is once again available for purchase.
- System Stability: General stability fixes have been implemented across all platforms to reduce crashes and performance hitches.
- Seasonal Alignment: The update maintains the current roadmap for Year 11 Season 2, which features the Dokkaebi Jegeo Payload rework and the Calypso Casino map.
For players on PlayStation 5, the update file size is relatively small, focusing primarily on these targeted hotfixes rather than introducing new content assets. These changes arrive mid-season to ensure the technical integrity of the competitive environment as Year 11 Season 2 continues.
