Where is the performance fix?

0.1 and 0.2 worked just fine performance wise. There's clearly something way off this league with the base performance and juiced end game maps are close to unplayable if you have a lot of abyss or haven't cleansed the maps yet to get rid of beyond mobs spawning.

Closing in on 2 weeks with complete garbage performance while mapping. I'm close to giving up even though otherwise the league is the best poe2 we have yet seen by a mile.
