I wouldn't call a 10 tick rate a bug. That's just appalling. Counter-Strike may be one of the very very few games that needs higher than 30. Hell many believe higher than 60 because it's that noticeable for twitch gameplay. Games like Battlefield and COD are a little different where they could get by with much less, but one would figure they'd have a tick rate of at least 30 for a FPS.
Insane mistake.
