Delirium maps are unplayable unless you have top-spec pc

I'm using GFN with pretty good processor and videocard(RTX 2080) (as example, I fully completed Cyberpunk on release with max graphic settings(without rtx though) with ~50-60 fps on release, pretty smoothly), but this game's optimisation is really bad at some aspects... like one of possible endgame activities - running delirium maps. Yep, current build isn't completed and I made some mistakes during this try (I know, you don't need to reply about this in comments), but still, I want to get smooth fps to enjoy this game, but thing I'm getting from this game is...

And the question is.. when will the game be optimized to be playable on good, but not top pc?

Update: Was in such tilt from staggers yesterday that even made this post XD Btw, it seems like main problem is in shaders.. Is it possible to, like, pregenerate all shaders for this game during first game load?(and stop generating 'em `on the fly`)... Or at least add option for this. (mb something like preload shader cache before entering map will be a good option too, but I'm not sure...)

Why does it show NVidia Tesla T10 as the GPU? That is pretty weird. It also doesn't show VRAM. Something seems off there.

In any case, I am getting better performance out of a 7700K / RX580 8GB combo I think. At least last time I tried, which was probably about a year ago.

out of all the content, poe crashes more frequently with delirium.

i dont mind crashing but the issue is whenever i crash my character is still in game so by the time i return i already lost 10% xp.

its up to the point i actively avoid delirium or end it early.

Firstly I agree this games performance is far south of good for the average aging gamer PC.

I turned all my settings down low in the past - but still delirium and some other game content gave unplayable frame rates / lag at times. So I tended to avoid this content like the plague.
Well this league it seems my Sirus and Uber Elder was getting a bit choppy too so I had a look at my settings again hoping to find a fix.
The one thing I missed/overlooked was resolution. I think I saw a demo of PoE being played on a SteamDeck and thought 'Why is that thing performing better than my rig' so I matched its resolution (went from 1920x1080 to 1280x800) and it has been my BIGGEST performance improvement playing this game.
I can now run the before laggy content with acceptable performance and my screen loads are very fast. I still get the odd visual bug where skills don't load in fast enough (usually uber boss skills) but otherwise I'm fine on my old rig. Just the graphics are a bit more potatoe'd.

older solid state drive
4G Wireless to Modem / Fibre connection

I lag a lot with delirium.
