FPS issues on Mac after 3.13.1 update

After updating to 3.13.0, the in-game FPS on my 2018 macbook pro was straight up unplayable at around 9 FPS, I constantly felt like I was playing a powerpoint presentation.

Since the issue with FPS was also occurring on my Windows machine (to a significantly less severe degree, but textures take a longer time to load compared to the pre-expansion client), I assumed it was some sort of optimization issue for both clients that was worse on Mac, where Vulkan is the only render option.

After updating to 3.13.1 today, I expected an increase in FPS because the patch notes listed some optimization on texture streaming. However, what I observed was even worse performance, with my FPS in my hideout bottoming at an amazing 2 FPS. Screenshot attached.





I know this machine is capable of running the game at very high graphics because I do run PoE in the exact same hardware on bootcamp when traveling, so this is likely some issue with optimization.
