Game capped to 28fps using DX12/Vulkan

I played on release in Mercenary League, and my game was running 60-80 fps on release (same with every other league ive played) but when I played the next day it was capped to 28 fps. The only way I can get above 28 fps is when running DX11, but is not stable enough for heavy currency strats with a lot of mobs. I have googled this issue and attempted all fixes ive found (Reslotting gpu, bios changes, disabling audio, minimum graphics, reinstalled graphics drivers, reinstalled the game, etc) and nothing has worked.
