ELDEN RING NIGHTREIGN Hotfix 1.03.5 Fixes Multiplayer Performance Bug
ELDEN RING NIGHTREIGN Hotfix 1.03.5 released on March 31, 2026 to fix a multiplayer performance bug that could affect every player in an Expedition. Bandai Namco says repeated use of specific actions could progressively degrade performance for the whole group, making this a small patch with potentially broad co-op impact. The hotfix targets PlayStation 4, PlayStation 5, Xbox One, Xbox Series X|S, and Steam. It is also mandatory for online play, so players who still see Regulation Ver. 1.03.5 missing should log in, apply the latest regulation data, and restart the game.
News summary
Hotfix 1.03.5 addresses one clearly defined multiplayer problem rather than delivering new content or balance changes. According to Bandai Namco, repeatedly using specific actions during a multiplayer Expedition could lead to degraded performance for all players in the session. That makes the fix relevant even to players who were not personally triggering the behavior. The update applies across the listed PlayStation, Xbox, and Steam versions, and Bandai Namco says it must be installed for online play.
Update overview
The fix removes the Expedition performance degradation caused by repeated specific actions. Bandai Namco does not identify those actions in the public note, so players should not assume a particular weapon, Nightfarer, skill, or route was responsible. The version display is also easy to misread: the title screen should show App Ver. 1.03.2 and Regulation Ver. 1.03.5. The hotfix number therefore matches the regulation version, not the app version.
Player notes
Console players can receive regulation files by logging in to the server. If Regulation Ver. 1.03.5 is not shown in the lower-right corner of the title screen, Bandai Namco instructs players to select LOGIN and apply the latest regulation before playing. After downloading the patch, restart the game so the update is properly applied. Because the update is required for online play, an outdated regulation version can explain why matchmaking or co-op access is unavailable even if the base game still launches.
Key details
Target platforms are PlayStation 4, PlayStation 5, Xbox One, Xbox Series X|S, and Steam. Release date: March 31, 2026. Expected title-screen versions: App Ver. 1.03.2 and Regulation Ver. 1.03.5. The fixed issue is a multiplayer Expedition bug where repeating specific actions could degrade performance for all players. This is not presented as a content patch, balance pass, or new Expedition feature. Players troubleshooting online access should verify the regulation number before changing unrelated network settings.
Trailer, screenshots, and media
Official NIGHTREIGN trailers show the three-player Expedition structure and combat context in which a session-wide performance problem would be especially disruptive. The videos do not document the hotfix itself, so the patch note is the authoritative source for the bug and required version numbers. Media is best used here to understand the co-op environment, not to infer which unspecified repeated actions caused the issue.
