I think I've figured out the issue. Somebody on the Discord posted that unplugging their GoXLR sorted the issue and I'm running Voicemeeter and disabling that fixed it for me. BO2 has always had weird audio issues so it makes sense.

From a bit more investigation it seems like I can continue to run Voicemeeter while playing BO2 as long as I'm not running any inputs through it, so it maybe seems like the extra inputs rather than outputs is the issue, so keep that in mind.

I'm having this issue too, have tried reinstalling and cycling between fullscreen/windowed.

For anybody Googling in the future, we managed to sort it out by disabling IW4MAdmin. If we figure out how to sort that out I'll update the post!

Hi all,

Trying to host a WaW server, everything works but we're having this issue with lag spikes. It sort of works okay at low population, but as soon as it gets above 4/5 players everyone gets yellow (cg_lagometer) spikes and the console is spammed with this error. Eventually the server will crash.

Any help much appreciated.
