Finally got all my shortcuts sorted with my controller, big picture working flawlessly, using xbox controller (yes controller, old hands no good with KnM these days lol) button remapper and set the share button to clip 30 seconds, press and hold to do general recording. all my other launcher games in steam now including epics fortnite which allows me to record too.

Can finally sit back and enjoy gaming with less distractions

Thank you valve for one of the best features and all the other features within Steam.

Only took me a good few years to realise that Big Picture is an awesome feature.
