It may have taken a while but Valve has admited to the stutter bug as described by many
Half-Life 2 users. The company has already released a patch through Steam which addresses
those issues.
The problem is described by Valve's Gary McTaggart as being
...actually three different bugs. Two of them are fixed and should (hopefully) be out
tomorrow. Still working on the third one which only happens on NVidia
cards/drivers.
The patch on offer now, through Steam, fixes the two main problems but
not the nVidia issue. In order to receive the update, users have to quit and reload
Steam.
