If your FPS is capped (45-50ish) using dx12/vulkan, READ THIS

I started playing PoE2 EA on release and for the first three days I had no issues at all. 120+ fps maxed out on everything at 1440p. Eventually either a GGG patch or a windows update happened and I logged on only to be capped at 50fps. Turning settings all the way down or up made zero difference at all. I fought this issue for days. I found out turning on DX11 would give me fps back but... of course it had all the dx11 issues and stuttering. Not a pleasant experience. If this has been you more or less, read on.

I found this thread:

Which was applicable for poe1. It however is definitely a fix. I built my PC a couple years ago and I suppose I never noticed I installed my M.2 into a 5.0 slot. It was using lanes from my GPU and upon looking at GPU-Z I was at x16. I was actually at x4 1.0. I swapped my SSD into M.2_2 and now I'm not only back where I was, I'm like 160 fps. All is well. Take a look and check your PCIE info fellas. Definitely worth a look.
