I love being able to toggle zoom
that client gave my a black screen when i got into a game, i could see the player team indicators and my crosshair and a few white bits but rest was blank, are there settings in there that are buggy? to save me a lot of 'trial and error' im thinking one of the AA settings must be faulty?
but overall I think the demo so far is good, dedicated servers are absolute pants mind, since 9 times out of 10 all I get is 'server full' or 'cannot connect to server'.
