I don't know if its a source problem or a PVK problem or MY problem. When voice chat is enabled in game and 2 or more people are talking, the game gets very laggy. If I disable voice in game, my game runs fine. My game worked fine prior to 2.3. I'm not sure what to do, so suggestions are welcome! I have a pretty new comp with a good graphics card, plenty of ram, etc etc etc. Ran the last PVK2 build fine on full settings, with voice chat.
