Arbiter of Ash is undoable with my current PC

This is for PoE2.

My PC is somewhat medium range, it has a GTX1650, RYZEN 5 5500 and 32G of Ram, and yet the game runs poorly on the lowest settings, some crashes, a lot of FPS problems and rendering problems. Right now I faced around 30 maps in a row which had invisible enemies that could still hit me even while rendering, constant lag (my character was teleporting around), a lot of enemy attacks especially boss attacks where completely invisible or just rendered a portion of the attack to the point they were barely noticeable on the screen.

All these problems were exacerbated inside citadel maps, all the citadel bosses had an invisible faze transition and some very poorly rendered attacks to the point they didn't even look like the bosses from the campaign. Arbiter of Ash especially was the worst, all his one-shot attacks which require positioning to avoid were almost impossible to figure out because there was no contrast between the non damaging zone and the damaging zone.

So I just lost around 20 hours of gameplay getting the crisis keys, just to enter the pinnacle boss, almost kill it, get one shot 5 times in a row because the attacks didn't render on my screen or worse, lagged my PC to a point were my character froze and the next second I was dead because of the boss mechanics which require me to see the boss.

People at GGG, sorry to say, but the game is lacking in performance, much love to all of you and please get me my Arbiter of Ash attempt back, I don't want to get another 3 crisis keys to die the same stupid way.
