I'm updating 4 times per second and the traffic stays pretty low so far.
I dont think you should aim for 56K modems , because when you finish your game they might be out of use...all my friends have better connections for lower prices.

...But since I'm not doing direct traces, but instead I use a scan and do back-traces, the whole thing is pretty tolerant.




You scan from one player for hit and then scan again from the other player to see if they're close enough ?
And , what does sometimes miss the enemy That sounds like you're doing FPS...

PS.: I've slowed down my mp development for a few days , because I needed some definitions of my concept. I now have the full list of features (What the player can do in the game) for my game , but I'll probably add more options later. I'm currently thinking how to manage the players. So far I have a skill to identify the ent as a 'player ent',but still testing to get some client ID's. Any ideas ? Oh, and btw , the MySQL dll is for older versions of MySQL , so dont count on that for registering/logging already tested and failed.
