What's with this sluggish gameplay, delays and ping?

Can y'all revert back the game to when it was at the beginning? This is so annoying and I can't play properly at all. The game starts with 144 FPS (My refresh rate) but when the game goes on, it drops to 115 and the game becomes sluggish as hell. Passes aren't reaching to where I aim, quick tactics not working at all, sudden 300+ ping boom when the game started on 12-16ms. I don't know what is even the problem anymore. This is just stressing everyone. Are PC players a joke? 

Not only that, was playing Gauntlet yesterday and won a game 2-1 extra time. It was so sweaty because of the gameplay. After the game's done, the screen was frozen without letting me out to the game exit menu (Like the one that comes after the game ends). I waited for 15 minutes and it still was frozen. So I restarted the game just to get a disconnection warning and 0-3 loss. Like what I even have to do? Do I need to buy a new PC just to play EAFC26 when the other games are buttery smooth?
