Massive, frequent lag spikes during multiplayer

[Anti-Sex Task Force]

I am experiencing a downright unplayable level of lag spikes. They happen every minute or less, and when they happen, for about five seconds the game almost completely stops, dropping initially to a couple FPS to under 0.2 at the end of the spike. Then everything was back to normal.

My first thought was throttling because this is a new PC, so I went ahead and stress tested my GPU and CPU - never went above 70. Also, there were exactly zero lag spikes when I was playing solo, no matter the intensity of the action on the screeen or elsewhere.

Any thoughts on what exactly is going on or how I can fix that? The game is nearly unplayable in multiplayer in this state.

Having this issue too, sad nobody has an anwser, from what I’ve seen it’s a AMD issue mostly

Did you ever find a solution to this? Having the same issue.

no solution yet but have the same issue here

Same issue here. Happens every time someone joins or leaves. Turned off crossplay but no change. Since the latest patch, I've noticed a LOT of people leaving suddenly in missions and I suspect it's because they are crashing too. I also had two back to back crash to desktops and I've almost never had those before with this game. Something in the last patch broke me, I'm convinced.

Bumping, same issue

Yup, complete ui/game freeze for three seconds from time to time, seriously annoying, nothing to do with people joining or leaving.

It's the windows update, need a fresh install
