looks good - what's the 75 tick mean though ?

Its the same as css. the higher the tic rate the better the reg and the less the lag and bullshit.
But the higher the ticrate the more uber pc and bandwith needed for the server.

ah ok I was thinking along the lines of tick as in tickets like in BF2 for some reason lol.

think 66 tick is default but not sure, so 75 is a little bit of an upgrade.

I'll play if your invite includes me !

In css the good servers use 100, or at least thats what I have been told.

Yes the best servers usually have 100 tick rate.
