Every time someone connects while I'm playing, the entire game freezes for a second. Since I mainly play on high population servers it tends to be come highly frustrating as it happens around 10 times per game, often resulting in my death.

To fix it I've tried to change browser (to IE), change the prefetching options in firefox, change cg_deferplayers, update the PB files yet nothing seems to work. On the official forums people are as oblivious as ever.

Anyone who has any idea what could be causing this? My FPS otherwise in the game is fine and my computer should be running the game without any problems.
