I can also add that it gets much worse during the splitting effect from the weekly event.
I also get microstutters as soon as my fps fluctuates. (This was an old issue I fixed by disabling fullscreen optimization of the vermintide2.exe, capping FPS at a number lower than what I get also fixes this issue.)
I’m having this problem too since the patch dropped. It’s happened in two of the three games I’ve played today. If it helps, I was playing the mission with Skarik Spinemanglr both times it happened, facing off against skaven about half way through the map. I was playing as mercenary kruber with the executioner sword. Not sure if any of that is relevant though.
I’m having the same issue. FPS keeps dropping from 60 to 30 in regular cycles throughout the whole level on every map and even in the keep as well. Although it’s more specific in the keep, it drops every time I exit and re-enter the central part of the keep, take a look at the video and watch the FPS counter in the top right corner
