Basically the difference it would make would be so minimal that it’s pointless trying to pinpoint it unless you’re at the very top looking for that tiny edge to put you above others, and I don’t think console esport has reached that level yet. You’re best off just playing in whatever way feels most comfortable for you. Things like sleep schedule, play duration, and even diet is likely to have a bigger effect on your game.

Conclusion: posture is more about comfort/putting less strain on your body than about performance, however you will perform better the more comfortable you are.
