Studdering just a bit, it seems it only happens when a couple of models load their higher or lower poly version based on my distance. Other than that though A+ job Valve! Those still complaining most likely have a slow PC.
I've noticed the stuttering has always occured in specific places. For instance, I'm thinking of the "pick up the can" area. Or when Dr. Breen begins speaking when you first step out of the train. What is going on in those areas?
Yeah, nice 12/22/04 patch!,, it made my stuttering problem worse than ever, as echoed by many other players in other forums.
I really wish I could undo that last update
