Performance issues

Been having some weird problems, Whenever i play an alt character the game lags so much i can't even walk inside my hideout, i switch to my main, the lag stops, i switch back, the lags comes back

I don't undestand this and i'm pissed

GGG please do something, i can't continue like this

imagine in the leauge trailer they did mention they sorted all performance issues by reducing amount of monsters by 40% while the game still filled with tons of useless mobs and perfomance still broken.

but some areas did have improvements so I dont lie but the improvements were 10 fps more ?


The act 3 maps alone dropping fps from 100 to 35 lock.
