Well, first of all, my ping seems to be locked on 98. No matter the server I'm playing on. I dunno if the client is locking the ping to 98, or if it's just the displayed ping which doesn't give my actual ping (with the regular client, I'm between 50 and 60 on european servers - I live in France). I tried to duplicate the packets, or to modify the values of sacc_rate and sacc_maxpackets, it didn't change anything.
Aside this, I have a question : can this rebuild really improve "hits" even if the server has regular settings (like maxpackets on 42 instead of 125 with the rebuild). In any case, with your rebuild, you're affected by the spec limitations of the server connection, isn't it ?
