Yes, when I am lucky enough to not disconnect from every other player I still get the exact same lag spikes too ZehDon. It's usually between 2 and 5 seconds or so. And any longer than 5 seconds and I usually get booted.
I am assuming there's a time limit as to how long you can "freeze" before the game boots you from the other players. But I don't have any idea what is causing the freezes or why. It has nothing seemingly to do with my CPU or video card. Everything is usually going just fine and then it will randomly freeze and sometimes boot me from the other players (At which point the game runs perfectly fine the rest of the time)
2.8ghz Intel P4 with H-T 800mhz FSB
512mb ATi Sapphire Radeon HD 2650
3.0 Gigs of 400mhz DDR2 RAM
160 gig SATA HDD (40 gigs free space)
I play in 1280x1024 resolution, 60mhz refresh, .... I use a Cable modem with Comcast ISP, and a Belkin Wireless router. (But I connect directly to it via ethernet cable)
Just in case it's relevant,
