Doesn't matter the area, pve, pvp, housing.
Sometimes you press a button and it get's delayed, or sometimes doesn't work at all. In this clip I pressed my netch, noticed it didn't go off and instantly stopped doing anything. It then went off about 4 seconds after I pressed my netch. I'm not lagging, as my bear is still attacking. This also happens with literally any interaction. Opening doors, changing the menu, jumping, etc.

I just went into my xbox settings and the test mode for my controller, to see if any buttons stick. It shows exactly when a button is pressed down and when it is released. I spammed everything for 5 minutes and there was no stick.
There is something going on in this game to where the button presses you do are either "stuck" in a limbo period or ignored completely.
I have an open nat. All ports recommended by eso are open. I use a hard line directly into my modem and a wired controller.
