Re: Is this normal?
I had some strange performance issues with Source games a couple years ago.
I fixed it by reinstalling steam.
You might want to try that. Just move your steamapps folder out of the steam folder, uninstall, then download and install the latest version of steam and move your steamapps folder back so you don't have to redownload all of your games.
Its worth a shot.
Deleting the game config files might help too (I think they're in the steamapps folder with each game).
