Steam Update - HL2 Troubleshooting

Steam News (thanks Frans) has word of a Steam update that will allow troubleshooting of the cache files for users experiencing problems running Half-Life 2, Half-Life: Source, or Counter-Strike: Source. They also have word on The Half-Life 2 Stuttering Problem: "We're also investigating a solution for the sound skipping problems a small number of users are running into. We'll have a solution for this as soon as possible."
