FC26 PC not playable

i've been a FIFA en EAFC career mode player for years now. But this year EA has really done it, its been a few weaks after launch now and the game is still unplayable. Running fine at first but then starts going to 5-10 FPS after a cutscene of half time. Sometimes IF i make it through one match, i have to restart the game before playing another one because i just know the match will start off with 5-10 FPS. Ive tried all settings, and to be honest the fact that the game runs fine at first says enough. Its just an issue with either CPU only running or the cheat engine everyones talking about. Whatever is causing the problem, EA isn't showing any faith in fixing it. And i'm not even surprised. It's a disgrace to be honest. Releasing the same game from last year with sometimes minor changes, re-implementing features that were already in older games and marketing them as new, or even removing much used features without any logical reason why. And than not even being able to make it run smoothly on the best of pc's. I'm done with this. I demand a refund and this will be the end of my 15 years of FIFA and EAFC experience. It's over for me. 

The refund is because of technical issues of course. It feels like a scam asking 70 euros for a game that doesn't work. The other issues, i knew of them before buying so that's on me
