The performance of this game is abysmal for no discernable reason

This is the first GGG game I've ever played and probably the last. If I could convince my bank that the $30 sent to GGG was from the unauthorized access of a scammer (which isn't far from the truth the way this game runs!) and reacquire my $, I just might do it.

How is it, with above rec specs (3070 / i7-11800H), that even at lowest graphic settings downscaled so far to 50% so that everything looks like I'm playing an 8-bit NES game that the FPS is STILL under 60 and tanks down to the 20s 30s because now there's 3 monsters on the screen instead of 2! OooOoOooh!

I can play other modern era games such as: Elden Ring, AC6, BG3, Cp2077, DIABLO FOUR (which has the opposite problem of this game, the gameplay stinks but HEY at least it runs!), Expedition 33, etc. with WAY less issues then PoE2.

It is NOT FUN losing maps over and over AND OVER from dying to some unseen force because the FPS tank to the teens... IN AN ARPG! Where death is just a millisecond away.

I've tried all the little game life hacks, this that and the other posted here and on Reddit with no substantial changes. Apparently there's an issue with 3070s and 0.3.0c? So I rolled back to 576.88 or whatever was posted about it, no meaningful impact. Vulkan/DX12 I can't tell a difference.

It's so incredibly frustrating because the game is very enjoyable... when it works... there's no sense in it running this poorly when the graphic fidelity isn't THAT high.
