I think part of it could also be my computer possibly being last-generation by this point, I can DM you an msinfo32 for you to pore over if need be. Any efforts to optimize Darktide would be appreciated as well.
There are also network problems to consider, but @Harridas’s thread already covers this in good enough detail. My playing on wifi doesn’t help.
These problems combined create an unstable and unplayable game. Most notably, these are issues I don’t have in Vermintide 2, aside from the odd disconnect.
