I Finally Experienced MicrostutteringAnd it's in Mass Effect 2. I've been running a SLI setup since the 6800GT and while there have been some trials and tribulations, I've been privileged enough to never experience any sort of stuttering in my history of PC gaming. Until tonight that is, when I sat down and decided to spend some quality time with Mass Effect 2, a game I've been neglecting for far too long. I now understand what you all mean by it being annoying as sin.
On the other hand, I've read it can be caused by drivers as well and I noticed Gigabyte recently updated a boatload of drivers for my board so I'm hoping that'll fix it.
