This site is a collection of information on a problem with Half-Life 2 that has plagued many players of this otherwise excellent game. This problem is characterized by a sudden massive drop in frame rate when turning corners or moving into new areas of the game. These drops are usually accompanied by looping or stuttering sound during the frame rate drop which is how most people become aware of the problem. Aside from these isolated drops in frame rate, the game is otherwise perfectly smooth. These sudden drops kill the immersion and lead to a very frustrating experience. Below you will find additional details on this problem, some theories, and all responses from Valve on this problem.

Valve's DougV has posted an update
on the Steam Users Forums:
We're still working on a fix and hope to have something available soon (but not before it's ready ;-)).
As of this morning, we've got 506 (open) Incidents in our Support database, we went through and opened all the tickets that were ever created (resolved or unresolved). If you have a ticket about this problem and have not attached an ms32info report, please do so (only 1/4 of the tickets included this info...it's not required but it's good info to for the dev team).
We also found someone near our offices that is having the problem and we are scheduling him to come in with their PC this week.
