Kyber has not been working well for me

Idk what’s happening, i got it 3 days ago, installed some mods, but now i can’t install any other mods, and i can’t even find them on the mods menu. I looked for “Battlefront Expanded - Kyber Collection (7.2)”, and nothing. It’s the same for all of the other popular mods.

Whenever i play on the official servers, i have tons of rubberbanding, and performance isn’t it. I can play vanilla at high settings going from 100-130 fps, but on kyber i get those fps only at low, and in some areas (theed palace, inside ships…) the framerate gets choppy and gets down to 60.

Idk, the content is 10/10, but i can’t play it for whatever reason.

Suggestions?
