Yet moving bullets to TCP would still improve lag issues. UDP being "here! Catch the packet and I don't care if you receive it!" just doesn't do it. A better connection won't help with that either. I am not sure what the effect of using TCP would be either actually. TCP is slower but above all UDP is a lot better for sending multicast/broadcast packets. Are the bullet packets sent to everyone individually (unicast) or using multicasts? If they are unicasts changing to TCP might be worth a try.
