Once i got the gtx 460 se hooked up and ready to go. The first thing i did was download the latest drivers (263.09) off the nvidia website. Upon restarting the computer everything was fine then. Downloaded the orange box and started playing some games, Half-life 2 ran perfectly, but once i got to TF2 the lag and stuttering began. I was running into some high dpc latency which made the game pretty much unplayable, so i did a little research and found out some people had no problems with older drivers. I'm pretty sure it's the nvidia drivers since i did a latency test without it installed and was never over 300ms. Once i had it installed i peaked from 3000ms - 6000ms+, weird thing is I'm using the onboard audio and i hear no stuttering while playing music or watching videos even though dpc goes up to 3kms. This only persists while playing games. Any idea for what's causing this? I may be bottle necking the gpu since my cpu is kind of old, but also did a fresh install of windows 7 and still having problems.
