There seems to be an issue with DOS2 and the wired Rotor Riot MFi controller i am using, playing on my iPhone via the steam link app. Basically, the controller initially works fine, but if I either close and reopen steam link, disconnect and reconnect the controller, or tab out of steam link long enough for it to force me to reconnect, the controller will no longer work with DOS2. The controller will work fine with steam link, just not DOS2 unless you fully restart the game. Other games don’t seem to have this issue.
