Thanks for the reply, this is a complete guess on my part as I am by no means a game dev or anything of the sort, but I imagine it is loading the games assets in and toward the end of that load it looks at your graphics settings to tailor the last piece toward your settings. I would guess that at this last bit it pulls the graphics settings and at the same time pulls the audio settings. Probably wrong, but that's how I imagine it working lol
I think it's actually storing that stuff in origin, and then pulls all the settings (probably after the boot level) so I think that's probably spot on!
