General end game feedback

Massive performance improvements on Xbox Series X is needed on end game the abyssal parts unplayable when 3 or 4 rare bosses spawn out. Ignited ground maps fps drops from the start. Oil grenades that ignite causes fps drops.
The worst of all going any further buffing/juicing maps past 2 exalted is unplayable.
Last thing every ten minutes or so, rubber banding lag/pause stutter. Before this part was written I did make sure its not my internet/WiFi.
For the most part for early access console its ok, just serious performance end game play ability is needed. GGG is on a path to a really great ARPG on console. Right now end game is impossible to finish/farm/juice its a bit of a disappointment to my addiction lol

But do understand early access
