xbox serie S , game dont work as soon you touch endgame

Hi , everything in the title , the game work okay all story long but as soon you arrive endgame the game doesn't work anymore its barely playable...

cant finish my 3rth floor sekima cause everything lagging soo hard and running at 10-15 fps and everything teleporting or stepping frame .
even by putting the game in fsr or nis , shadow + global or without global , iv've try every setting possible , how they expect us to enjoy a game that doesn't even work at the best part of the game...

with endgame map , i constantly have to play with the setting and there no way to play with a satisfying experience like in the early game .... NIS look soo good but cant barely use it in half the game cause it lag in half the map and fsr look like a blurry mess and even activating it doesn't help with the lag .

sure you get 50-60 fps when your not moving and nothing happening on screen , but as soon there few monster or the environment is bit more beautiful (act 2-3) the fps tank to 10 to 30fps if lucky and everything skipping frame and looking weird.

im genuinely disappointed in the performance , i was soo hype to arrive endgame , but its quite litteraly "endgame" cause i cant even play anymore since performance fall down soo much , i guess im gonna do another characters or just stop playing either way.... the story was cool and all but the game was not properly tested for serie S and i dont expect update to fixx it soon enough since serie S always last in priority for dev.

I’m on 6-7’s with some juicing

I’ve added elsewhere, have both versions. PC is smooth. Series X is not.

I did hook my laptop up to my tv and with it not being 120hz it could not keep up (kept laptop screen going too). Purposely activated breach and while my laptop monitor did just fine, tv couldn’t keep up.

On series X-running it at 30 helps somewhat, still plenty of tearing and certain particles (blood tornadoes in rituals) really turn things into a slog.

At the end of the day I feel I’m left with the choice of springing for a monitor (I prefer larger screen and would rather play from my recliner) or a 120hz tv (which I’m not 100% confident will fix the problem with console). I’m fortunate that I can do either or both of those things, but not everybody is. Considering said tv has no problems with Cyberpunk/D4 though feel optimization really needs to be worked on. I understand it’s EA, so hopefully improvements will be coming.

yeah the problem is more soo that the game cant keep up with explosion or even when you kill a elite in endgame the animation of coruption make everything lag... i play some other crazy game , the comparison is not perfect but i play warframe max out with explosion ripping the entire screen off vs lvl 200 enemy with like 200 enemy shooting on me and there's absolutly 0 lag , the fact the tiniest animation even the dead of enemy make the game frame drop soo much that i die cause enemy animation doesn't even show off or lag soo hard i cant see it is frustrating , i know this is early access but when they said they put everything in the endgame i expect it to work.

EA is no excuse , all early access game i purchase before needed update and tweak its completely normal but they should in the bare minimum be playable soo the player can give actual gameplay fedback .
