There's a big difference between network latency and input lag. Taking 100 ms for the server to register a hit on an opponent is annoying, but acceptable. Taking 100ms for the game to notice me moving my mouse to the left and shift my view is not.

Ok, so input lag will be 2*your ping. An input lag <40ms is barely perceivable and 40-80 is playable.

So, you'll need a ~20 ping, which is reasonable for a fast connection.

Input lag is actually equal to your ping. Ping measures round-trip time.

I don't know what my input lag was during gameplay, but it was certainly enough to be noticeable.
