FC 26 PC Crossplay Delay

I am starting to lose my mind over the number of inconsistencies within this game, especially when it comes to connectivity, delay and overall lag.

I'd like to start by saying that I have taken every single little detail that could potentially affect my delay into account. I have:

10gbps USB-C Cable plugged into a brand new PS5 Gen 2 controller
4080 Super, i7-13700KF, 32GB DDR5 Ram, FC installed on an SSD
Frames capped at 120fps, Refresh rate capped at 120Hz with stretched res
Fixed Ethernet that sits at 12ms in-game

Yet I still consistently receive stuttering, freezes, input delay and sometimes outright crashes.

Now, unfortunately for me, I play on OCE, where the amount of PC players falls extremely short of those on console, which means the majority of my games are cross-play. Which is where the problem starts.

EVERY SINGLE GAME against an opponent on cross-play is absolute rubbish, with the most obvious DDA and delay I have ever seen and felt. Issues like:

Players I am controlling are getting pulled out of the passing lane they were cutting, allowing opponents to easily play through balls and passes right through my players.
My player's first touch is appalling, genuinely pathetic, even when holding/pressing nothing from a regular pass with tiki-taka plus.
Extremely obvious favouring in my opponent's actions
My players (e.g. 87 Dumornay) feeling like a bus, not being able to turn and getting outpaced by players with 15-20 less pace
Inputs are being straight out ignored, having to press pass 2-3 times in moments to get the ball moving

The game is genuinely different whenever I am playing a cross-play opponent, and I am sick of it. It's like my PC gameplay is capped to the max output of the console version of the game, which, when you compare the two, is laughable.

Can't believe this game costs money, and has an E-Sports scene, this game??! E-SPORTS?? It feels different every day; it's like they micro "patch" the game every 24 hours. Losing my mind.
