Online Input Lag (fixed and broke again)

Hello, when i first started i noticed a huge input delay, but only on rivals at the start (didn't play other gamemodes online then), I searched the internet to find a fix and founf multiple people with the same problem dating back to the 2/3 week of game launch.
I also used chatGPT to try fix my problem, here is the full convo and all i did to my computer: https://chatgpt.com/gg/v/6924f87af06c8194937c20cb46e56d43?token=nml8M_gExY-fwi_uxW-45

After all of it, i tried tweaking the in-game settings again (i did it at the start but didn't work) and found that when putting refresh rate on 120 hz and fps limit at 90 the input lag was gone. i played my games and after awhile i went into rush. There I faced the same problem my game was with input lag again but only on rush, I changed the settings and found that turning vsync on worked for awhile but eventually the problem return, then i turned vsync to 33% and it worked again. After that i went into rivals and i had input lag again, changing into my original 90fps/120hz didn't work this time and so, here I am. 
Hypothesis: The game or engine is poorly optimized for computers with external monitors or has difficulty converting refresh rates, a user on reddit found that when he game streams on a tablet the issue is nullified or least noticeable: https://www.reddit.com/r/EASportsFC/comments/1npg5mw/comment/ng0d5e3/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button
Everyone seeing this please like and comment to reach more people and pottencially EA devs.
To the devs: Thank you for the work put into this game and i know this issues are hard but i would still ask for more transparency and communication with the community. Even if the news are bad ones like "this issue is taking long to fix but we are trying :)"
