From Software’s DLC for Elden Ring, Shadow of the Erdtree, has been facing performance issues for PC since it launched last week. It appears that the issues may be due to external mouse-control software that players are using.
The official Japanese From Software Player Support X/Twitter account further explains how this may be the issue that PC players are running into. The tweet (machine-translated) reads:
“[ELDEN RING] In the PC version, the frame rate may not be stable when playing the game while running a mouse-control related app. In that case, please try playing the game after stopping the mouse-control related app.”
