The problum with ping judging games is the fact that an oc 3 with ping of 100 is quicker responding than say a 56k modem at 100 ping. Thats why new games need network management apps built in.
cause the two have same ping doesn't mean there running same speed
why they should judge with ping and internet speed both
They do this on css and hl2 using set network speed and ping to server, but its still very inaccurate. It wouldn't be as inaccurate if they were managed as one, using some kind of gaming network management software optimized and built intoeach online game.
