TBH.
For ten years I have been playing with hp pavillon notebooks that are not designed for gaming.
I tend to really pick huge custom databases, and play with 6 European leagues, 2 South American leagues, MLS and one rich league (China/Arabia).
FM gives me half a star out of 5. But the game remains smooth.
I do hate SI because they're slaughtering the gameplay in the late editions, especially over the long term, but the optimization is top notch.
I don't know this will change for FM25, but I doubt it, as you will continue to watch only one match at a time.
I suggest the best desktop pc you can afford. Best if it is an assembled one. Look especially at ram and cpu.
Oh, I almost forgot. You do deserve to be shouted
