When you keep seeing on the replay that you've been tracked through the wall / totally opaque smoke, and shot in the head with the first shot, at the very corner of the wall the very second you finally decide to take a peek out, when you were silently sneaking and had even waited a bit, then you know the game has a severe problem that they're just not able to keep on top of.

At least in Quake Live if you're good you can still beat one of the rare cheaters that crop up by knowing the map better, stacking up your armour and out playing them, and server ops are usually pretty on the ball if VAC is lagging behind.

Refunded.
