anyone else having problems with their sound in game? it glitches up on me, mostly during the first 5 minutes of play. It sounds like the voice/effect stutters. No drop in frame rate, just sound. I have a 5.1 Turtle beach santa cruz sound card, a 9800 Pro 128MB video card a 2.6 Ghz Processor and 512MB of ram. I think it may be due to the 512 RAM i ordered another 512MB so hopefully that fixes it.
