Warping is caused by network issues. You can try to get players use proper maxpackets setting. For example if player has 125 FPS, the value to use would be 63. If he uses 100, he is still sending the 62-63 packets in a second but if he gets FPS drop to below or equal to 100, he will be sending them 100 times (or his FPS amount) in a second. It combined with delays and possible buffering by ISP, can cause sudden faster moves then regularly. Do note that the packet sizes are typically irrelevant as the packets are very small and it would be a rare case if someone wouldn't have bandwidth for the data. The packet count is the bad thing as each of them can be buffered and delayed to give way for higher priority traffic.
