Last Ritual almost crashs my game

So far this happened in every last Ritual that I ran. As soon as I start the Ritual my game starts to lag, resulting in 1 frame every 10 or 20 secs. I need to Alt + F4 and relog.

I'm running an Arch Linux derivate.

EDIT: It's not necessarily the last Ritual that lags.

EDIT: Problem seems to be happening with Vulkan. Swapping to Dx12 fixed it.
