Performance

Would it be possible to return to 3.26 state of development and cut away all changes from 3.27? For me the game became unplayable with 3.27. Constant Vulcan crashes and horrible performance of Direct11 and 12. My PC is a Threadripper 2950x with 32 gigs of ram, Intel B580 12 gigs graphics card. The game is installed on a separate SSD. Some parts of the game seem to get worse and worse. For example in the maps I cannot see the mapmods anymore. They are just not there when I press TAB. I have already checked the Packs, but it says everything is fine. No matter what graphics settings I change, the performance is the same all the time. 120 FPS in the hideout and 5 Fps in maps if the screen gets crowded or the 3.27 breach mechanic is activated. Every other game i have runs perfectly fine as before, but Path of Exile I got such a massive performance hit that sometimes I think i got a PC from the 90's.
