I've been using the mumble 1.0.0 beta with project reality. At first it worked perfectly, no lag or anything. Now it's laggy as hell - I can't hear what anyone is saying and they can't hear me due to the lag. I've tried lowering the quality, I've tried tampering with the network settings and I'm stuck on what I should do.
I checked my latency to the server and I get the following:

I'm using 64 bit vista.
any help would be appreciated
Please note that my ping on teamspeak/ventrilo is perfectly fine, all other VOIP clients including the ingame bf2 works perfectly fine
