Very Bad FPS, Cluttered and Jittered Gameplay

Not only me but all social accounts, game friends have reported this. Game has a massive memeory leak with too bad FPS optimization. When you enter town FPS goes to 35, When you get close to the end game FPS goes to 15, when 2 players join you and you all are lvl 50 above game goes nuts with 12-25 fps(more enemies and more spell usage make FPS goes too low and unplayable). A MASSIVE TURNDOWN FOR THE COMMUNITY WHO WANTS TO ENJOY THE FLUID GAMEPLAY. Not a fan of Diablo but they have this thing sorted out. GGG we really love you. but you need to fix this an make game more fluid and smooth rather tahn making it more complicated. Kindly dont let us all regret our support. at this stage we are unable to enjoy PoE2

NOTE: This problem is observed across all types of machines starting from GTX1060 to all the way RTX4060 (medium to High end processosrs). And yes community who is facing this has no problem running even the toughest of the titles in the industry. seems like we are running GTA 6 and not PoE2.

i get 90FPS in town with a >>

-AMD 7900 12/24core@65Watts ECO Mode
-RX7600 undervolted
-96GB 6000mts DDR5
-Aorus 870E Pro Ice

Easy 120FPS-160FPS in Maps (FSR-Balanced)

The computer does not even heat up.

BUT !!

when i start using ICE or FIRE, FPS drop´s down to ~30 FPS

My wonderful AMD 7900 Temp. limited to 68C runs almost every game easy if Multithreaded without starting the Fans...

This game here, POE2 is the only game that causes trouble and even shuts down a new computer and my old one too...

Yes it gets cluttered and even highest build drops to 25 fps true. GGG must work on this as it has a huge negative impact on fun. This needs to get resolved ASAP.
