Riot Fixes Champions Shanghai Mouse Issues

Riot Games has replaced the problematic desk tops at VALORANT Champions Shanghai after repeated mouse interference disrupted matches and triggered multiple technical pauses during the group stage.

The issue was eventually traced to specific metal components used in the custom tournament desks. Riot temporarily asked players to switch from wireless mice to wired connections while a permanent fix was prepared.

By October 2, new desk tops had been installed. VALORANT Esports head Leo Faria later reported that no further mouse issues had appeared after the swap, with Riot continuing to monitor the setup ahead of the Champions playoffs.

The timing matters. The playoff stage begins on October 7, giving Riot several days to confirm that one of the tournament's most disruptive technical problems is no longer affecting competitive play.

What caused the mouse problems at Champions Shanghai?

The problems began during the opening days of Champions Shanghai, when players reported mouse and input issues during matches.

Riot's technical investigation eventually pointed to the desks themselves.

According to Riot, specific metal components in the construction of the custom stage desks were causing interference with player peripherals. Earlier communication also described the problem as a conductivity issue related to the desk material.

The exact radio-frequency mechanism was not publicly detailed, so it would be inaccurate to describe the desks as blocking signals in one specific technical way. What Riot did confirm was the connection between the desk construction and the mouse interference.

A temporary fix initially appeared to improve the situation, but the problems did not disappear completely.

Riot asked players to use wired mice

On October 1, Riot took a more direct approach.

Players at Champions Shanghai were asked to use wired mouse connections while the tournament staff worked on replacing the custom metal desks with an alternative setup.

Riot acknowledged that this was far from ideal.

For professional players, a mouse is not simply a peripheral that can be changed without consequence. Cable resistance, weight distribution, grip, sensitivity and years of muscle memory can all affect how a player performs.

Many modern esports professionals use wireless mice specifically because they remove cable drag during fast movements.

Switching to a wired connection in the middle of the biggest VALORANT tournament of the year therefore solved one problem while potentially creating another competitive adjustment for players.

Riot still considered it the safest temporary option while the desks were being replaced.

The FUT vs 100 Thieves incident raised the stakes

The desk issue became much more controversial during FUT Esports' series against 100 Thieves.

During round two on Split, FUT player Doğan "xeus" Gözgen experienced a technical problem that affected his ability to fire his weapon during a key moment.

The round continued instead of being rolled back.

100 Thieves went on to win the series 2-0.

After reviewing the incident, Riot admitted that the round should have been rolled back. The tournament organizer accepted responsibility for the officiating decision but chose not to change the final result of the match.

Riot's reasoning was that overturning the series would also penalize 100 Thieves, who had played under the same tournament conditions and were not responsible for the technical failure.

The decision left the result intact while adding a competitive-integrity controversy to what had already become a major production problem.

Riot said Champions had fallen below its own standard

Riot's public response went beyond a routine technical update.

The company acknowledged that the experience at Champions had not met the standard expected for players or fans.

That admission reflected how disruptive the problem had become.

Technical pauses had appeared across multiple matches, players had publicly complained about equipment problems, and the FUT incident demonstrated that a peripheral failure could directly affect an important competitive round.

For an ordinary online match, a mouse malfunction is frustrating.

At Champions, where one round can influence qualification for the world championship playoffs, the consequences are much larger.

New desk tops were installed on October 2

Riot's permanent response was to replace the desk tops.

New surfaces were installed before the October 2 matches, and players were given the option to test wireless mice again.

The plan was straightforward: if mouse stuttering returned, the event would immediately revert to wired connections.

After the replacement, Faria reported that Riot had seen no further mouse issues.

That was the first strong indication that changing the desks had addressed the underlying problem rather than simply reducing its frequency.

Riot said it would continue monitoring the stage setup.

The desks were not made by Secretlab

The controversy also created confusion over who supplied the tournament desks.

Secretlab is involved with Champions Shanghai as a chair partner, leading some viewers to incorrectly associate the company with the problematic desks.

Riot later clarified that the desks were custom fabricated by Riot for the event.

They were not manufactured, supplied or sponsored by Secretlab.

Secretlab's involvement at Champions is limited to chairs, not the desks linked to the mouse interference.

Can Champions players use wireless mice again?

Yes, based on Riot's latest update.

After the new desk tops were installed, players were allowed to return to wireless connections as a test of the replacement setup.

Riot reported no mouse issues after the swap.

That is an important change from the temporary October 1 policy, when wired connections were requested across the tournament to minimize the risk of further interference.

The situation is still being monitored, but the available evidence suggests that the replacement desks solved the problem before the playoff stage.

Why the issue matters beyond one broken mouse

The biggest concern was never simply whether wireless mice could function on a metal desk.

Champions is the most important VALORANT tournament of the season, and the equipment conditions are expected to be consistent for every player.

When a technical problem changes how a player can interact with the game, competitive integrity becomes part of the story.

That is especially true when the temporary solution also changes a player's normal setup.

Professional players spend thousands of hours building muscle memory around specific peripherals. Even a familiar mouse can feel different when a cable is introduced.

The FUT vs 100 Thieves incident made that concern impossible to treat as theoretical. Riot itself later concluded that a rollback should have happened.

Is the problem fixed before the Champions playoffs?

As of October 5, the answer appears to be yes.

The replacement desk tops were installed on October 2, wireless mice were tested again, and Riot subsequently reported no further mouse problems.

The tournament now has a two-day break before the playoffs begin on October 7.

That gives organizers additional time to monitor the new setup before NRG vs T1 opens the final eight.

The technical story may not disappear completely from Champions Shanghai, especially after the controversy surrounding FUT and 100 Thieves. But the immediate hardware problem that forced players onto wired mice appears to have been resolved before the tournament's most important stage.
