This is with the demo.
Anyone else experience what I would describe as a high frequency buzzing sound when there seems to be a high load on the soundcard / PC? Seems to occur most frequently when I'm looking towards action/hearing a lot of loud sound effects.
I've updated my sound card drivers, have a Sound Blaster X-Fi Xtreme PCI Express. Running on a 780i FTW, Q9550 @ 3.83 ghz, GTX 280 SSC and 4 gigs ram.
