Before: 80-90 fps (lobby. DX11).
After: 40-60 fps (lobby, DX11).
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.)
