For the last couple of months I have been experiencing extreme "slow-down" issues along with "static-like" sound in my 3D games. The slow-down seems to occur along the same time the static sounds start up during these games. I notice the static sounds constantly when there are low-frequency sounds produced in the game (i.e. explosions, ambient low frequency tones, deep footsteps on a metal flooring, etc.). I installed the latest 195.62 NVIDIA drivers and have reinstalled them...I have the latest Realtek HD Audio drivers as well. Still none of these fixed my problems.
I experience these problems across all my games (Mass Effect, Batman Arkham Asylum, ...and now Dragon Age). Mass Effect used to work fine...so did Batman. So, after considering all the problems I experienced along with many others late last year (reference this 10 page forum discussion with several responses from BitDefender (http://forum.bitdefender.com/index.php?showtopic=16648), I thought maybe the static sounds and slow-down in my games was also from BitDefender Antivirus 2010.
So, I just now uninstalled BD Antivirus 2010 and everything works fine now. Unfortunately, it looks like my suspicions are correct. Something is messing with these games and I believe it came from a BD Antivirus 2010 patch...I'm almost 100% sure of it. If others out there have experienced this, please post here. I am a frequent gamer, so this problem is unacceptable.
