Yes, it does! I've been playing just with dealge + granades for last month (or more), but almost every time somebody calls me a cheater, because i get a lot of headshots... I tink there is something seriously f*cked up with hitboxes, because sometimes a player is targeting at legs and he gets a headshot... Ofcourse hitboxes in cs 1.x weren't perfect either, but there were not as much headshots as in css...
