I had this problem big time on my stock Dell Dimension 3000. One of the trainer guys typed for me to disconnect and relog in as he said I was all over the place warping. Well, I didn't know who he was and basically said (in buffer text) to blow it out his ear. I've come across some people in here that for their $15 per month like to try to play BS with me, and tell me how I should play the game (to benefit themselves). I typed back to please explain, but I got no response.
Dropping my firewall seemed to help some as to less plane warping. Dropping my antivirus did not. The larger ping numbers would result in more of a problem. For me it always would be worse as numbers of planes increased and the addition of mutiple tracer rounds, especially in zoom. Turning off tracers also hepled, a little.
Since, I got me a $140 graphics card upgrade and things don't warp as bad.
Prior to coming here I upped my ram from 250 meg to a gig of matched pair 512 sticks. Would be better to get 2 gig of matched 1 gig sticks, but I'll just get a better PC one of these days. I'm on DSL.
Other note, I hang out to the geek forums for XP. Somebody suggested Windows needs to be re-logged every 4 hours or so as it bogs down. I don't know if this is the issue or not.
