FromSoftware has warned players that performance issues experienced while playing Elden Ring’s Shadow of the Erdtree DLC may be caused by computer mouse software running in the background.

Shadow of the Erdtree released to critical acclaim on June 21 with IGN's review awarding the expansion a 10. However, many in the community have since complained about significant performance issues on both console and PC, which contributed to a review bombing that saw the DLC slip to a ‘mixed’ overall user rating on Steam.

According to a recent FromSoftware tweet, these issues may partially be remedied by closing any third-party computer mouse software prior to launching the game. “In the PC version, the frame-rate may not be stable when playing the game while running a mouse-control related app,” read the tweet, as translated via Google Translate. “In that case, please try playing the game after stopping the mouse-control related app.”

【ELDEN RING】PC版において、マウス制御関連のアプリを起動している状態でゲームをプレイするとフレームレートが安定しない場合がございます。その場合、マウス制御関連のアプリを停止してゲームプレイをお試しいただきますようお願いいたします。

As reported by Automaton, some players had stumbled across the suggested fix earlier this week after running into stuttering issues while using mouse gesture software. FromSoftware has also noted that players should check to see whether ray-tracing settings had been enabled erroneously on their PCs upon loading save data from a previous version of the game, which could contribute to unstable frame-rates.

Further bug fixes and balance adjustments are planned to be rolled out in future updates. Check out IGN’s guide detailing the best settings with which to take on the Shadow of the Erdtree DLC on console and PC.

Performance issues aside, Shadow of the Erdtree is off to a phenomenal start, with publisher Bandai Namco announcing earlier this week that the DLC had sold over five million copies in the three days.
