Performance drop multiplayer (seems to happen after dying??)

[Game__On 10]

So, i'll be playing with kind of smooth frames, then after dying when i get back performance has halved.

OR, maybe it just happens after a short period of time anyway, who knows but it SEEMS like it's happening right after dying .

Now, my system is

3770 k

8 GB Ram

gtx 680's (in sli)

Windows 64 bit

And arma is installed on an SSD .

Temps are fine, plenty of memory available when playing (nor sure about graphical memory though, i have 2 GB available total) , and exiting arma and then going back does NOT resolve the issue.

Only a full reboot does.

Oh and sometimes the crappy performance is accompanied by failing audio as well.

What can i do ?
