I've attached a link to a clip that shows my problem. I've tried a few fixes such as:Дisabling/enabling shader cache in Nvidia Control Panel Sometimes the game runs perfectly fine, which means my connection. I have 200mb connection, all the ports forwarded properly and get 18-20ms green ping in the matchmaking screen. Input lag makes the game basically impossible to play properly.

However, upon re-downloading the game and playing through both Origin and Steam's versions, I am constantly hit with lag spikes and stuttering in all game modes, online and single-player. This weekend every single WL match has been a nightmare. (can even run Cyberpunk 2077 at decent frames) Problem seems to get worse in conflict,but it's still very present while there's no action. I've recently re-downloaded Battlefront 2 after having played it before in both 20, no issues, same exact system setup: I have problem with Battlefront 2.When I play in singleplayer,game works great-4K Max settings,60FPS,but once I start playing Multiplayer,I got huge stuttering,FPS drops and lags.
