I have only played a little of it like 3 games.
I used the BF5 ST and it was acceptable. Not perfect, but acceptable.
I reduced the deadzone in game for right stick to 10
Instead of adjusting my BF5 config in Xim, I just adjusted the game to work with what I had, the ADS is a little over sensitive and although there appears to be no aim assist menu, I certainly felt some AA when I played a little with controller for a few minutes to see how it felt.
Now I am about to try it on PC to see if my PC performance can match that of the XBSX , I doubt it some how.
As suspected XBSX wins the war against a R2700X 32GB Ram and rtx 2080ti :-)
