ok so let me explain everything, the modpack boots up like normal, nothing is out of the ordinary, and it runs a good speed, creating the world, same result, the problem is when i get to play the world, for some seconds it runs fine and normal, but then suddenly it goes like 0 fps and causes a extreme, unplayable lag for no reason, i dont know whats causing, i have tried downgrading, didnt work, adding optifine, didnt work(tho it allowed to turn on the lagometer, which when it lags, i can see very giant cyan spikes, and that mean that the problem is the ticks)
It happens in every world, no matter if i dont even have ANY machine, it just lags at unplayable speeds and frozes for no reason(atleast that i could find) so i dont know exactly whats causing it, any solution? i can send my config or logs if requested

nvm it was xaeros minimap causing it for some reason, removing it solved the issue, leaving this here in case anyone has the same problen c:
