Performance is still a large issue.

I seem to have an inconsistent experience in terms of graphics and performance in this game and I just don't know what to do.

I have a 5800X3D and 7800XT and plenty of RAM. I play at 21:9 on a 3440x1440 monitor.

My major complaint is that there are just too many scenarios that bring me from a stable FPS (anywhere between 70-130, depending on what's going on) down to literally less than 1. It doesn't even have to be chaos on the screen, it can happen if I walk over and see the wrong mobs in the wrong place.

The game turns into a slideshow where my inputs are not processed.

I have tried different upscaling - FSR, NIS, lowered the resolution while keeping the ratio the same, used dynamic culling, dynamic resolution, turned all settings to the lowest they can go and all sorts of combinations - nothing is helping with this issue.

So far the "best" outcome has been using FSR with everything else on default. It gets rid of the shimmering weirdness that comes with using NIS, but instead it makes everything look faded and washed out/blurry but even then, I'm being pretty cavalier with the term "best". It's just sometimes it goes down to 6 FPS instead of 0.

Somethings I noticed that really flare up the performance problems:

- Karui mobs with "auras" around other monsters.

- Heart of the Tribe zone in act 4, almost always has a "problem area" I have to slowly bait mobs out of because I can't go closer without going down to 0.3 FPS. Once the monsters are dead, usually I can walk through it but still experience a pretty noticeable FPS drop.

- Lighting Storm on top of Accelerated Growth Entangle with bunch of shock/chaining/living lightning support.

- Grimhaven and Bastille maps frequently have problem areas/monsters.

- I've had it where I wandered straight into a "problem" area while having a gloom shrine, and apparently I killed all the monsters with AoE because in the next frame (4 seconds later) I heard the pop and lo and behold, all my performance issues were magically gone, along with all the corpses. This leads me to believe that the issue is surrounding some character models and their corpses.

- Corruption maps. When the corrupted monsters spawn in, especially with a lot of other nonsense going on.

- Slamming down an empowered sunder onto an erupting Abyss while having herald of ash buff enabled. Basically get up to stretch and sit back down and hope I'm still alive.

Does anyone else experience this? Wondering if it's related to my settings or hardware or if anyone with similar hardware has similar issues.

Looking for any solutions or ideas as well as giving feedback.

I've heard that maybe my issue revolves around playing in 21:9... Been avoiding playing "windowed" but maybe I'm just delaying the inevitable...

Game looks great otherwise though. Really just the moments when my computer decides to have a hernia, which is extremely often during endgame mapping.
