There is an obvious flaw in the source engine and its been over a week since there has been an update, i mean i am actually beginning to be quite concerned and losing faith with valve. I mean this is a joke, nearly 4 weeks and i still don't feel the game is in a playable state. This has nevered happened before with any game i have bought for the PC so is this it? The final product, if you don't like it buy a new PC? I really don't see this being solved completey anytime in the future. I hate to do it but i might just ruin the whole hl2 experince and just play through the game and make do with what i got. So much for forking out on a top PC, I have learned my lesson and a hard one at that. Anyone else on the same boat?
