I'm having major lag issues on every server I try.. even the lowest pinging servers (70-90) do this:
 
 (with no one around me.. even on empty server)
 I press a direction - foward for example : I move foward then the engine pops me back to where I started from. 
 
 I know it should do this when I'm lagging to keep up, but it seems I'm always lagging. I have a cable modem, and a fairly nice system.
 
 Its completely impossible for me to move around, and when on those maps with the "fall to your death" platforms... I fall everytime, because it always throws me around (and it's not the force powers - again - it does this when I'm the only person on the serer). I play Q3 and never had issues this bad. Is there something in the config to help me?? I have it set to "lan/cable" also.
 
 
 my system: 
 
 750 AMD Athlon
 Voodoo 5
 512 Ram
 RoadRunner - Cable Modem
