MW3 Coop Survival Private Match Issues

[iamdna]

Hi there, I am having some problems when I try to play a co-op survival private match at Spec Ops. Sometimes it's like me and the other gorgeous player are playing a different match even though we start perfectly synced. We end up fighting "alone", because for some reason the other player (either me or her) starts acting weird.
Example:
We are at the 4th wave when I see from my screen that she is always crouching and shooting at the ground, when she is actually playing normally on her pc. We realized this was happening quite often but haven't found any solution to that.

Also when we try to speak through steam voice chat, it is almost impossible to play without lagging. Is the voice chat consumes so much of the internet connection? Does anyone else has this kind of issues?

Also here is a video I uploaded as an example:

At this moment (on the video) she told me that not all the hostiles of the previews wave are dead, while I am having a countdown on my screen for the next wave.

It is the in-famous out-of-sync bug.

You can try to limit the number of sent packets from default ~800-1000 to 100.

seta cl_maxpackets "100"

And maybe set this value to 2. Default is 0.

seta cl_packetdup "2"
