Just downloaded from MS site and I went in to check out game mode in settings and it's gone. Well there is a bit to read but no settings or anything. Can you only get to it in game now? I don't use the bar that comes up in games though obviously because of Steam. Any news on what's happened? I guess it's just integrated and that's that. Also I don't know if it's me but my mouse seems to have gone faster. No acceleration on and went into Logitech software and all is as it should there.
