I played HL2 when it first came out years and years ago. I now got the Orange Box pack and installed it, let steam update everything etc. Started a new game and immediately noticed something funny about movement. Basically if you press a key to move and let go of said key, your on screen character doesn't immediately stop on letting go of the key, he carries on moving for a bit, a sort of inertia effect. Now I don't remember movement being like this when I first played it, although it may just be my memory playing up. The same thing applies to TF2 so it appears to be an engine thing. Is this normal or can it be switched off? I'm not at my home pc now so I can't try this, but could it be anything to do with vertical sync being on causing keyboard lag or something? Bloody annoying whatever it is.
