Hello m8s,
without long stories.....
We have diplomacy v1.1 and experience out of sync every 2 hours of game.So we download latest patch v1.11 or something and....we experience same out of sync problem.Then some of us read the patch note:).Imho fix is useless if u play with friends in lan party and that is not my opinion but fact.
Anyway our rate of sickness reach the top and we decide to act and make our own fix.
First and most obvious thing to us is autosave.So we focus on it.And we found there is size difference in players autosaves.For example one of us have autosave7 in size 6,75mb and second in 6.74 mb etc,all saved in same time.And after this autosave very soon game vent out of sync.
So we disable autosave for every player and also autorecord.We do that from user.settings. (and diplomacy users setting,do it in both)
Now we have 3x 8 hours games done without any single desync problem,minidump or anything.Also we try this on version 1.0 and 1.1 and same.No desync at all.I dont know what exactly happen wrong with autosaves and why that happen,but many online RTS strategies have their weak spot especially in autosaves.Next thing is hardware latency and i believe this play big role in sins.Especially in later parts of game users with GFXs in SLI/Crossfire may ruin game for others,because their gfx latency is 2 times bigger.Considering size,hardware and internet traffic demans,differences betwen players hardware and after all Sins emulating same speed for all players..............autosaves are deadly trap!
And other small advice,pause game after 45min of playing and save it.Its good,coz u have disabled autosave:) and pause may help stabilize things and saving during pause is also good thing for obvious reasons.
Try it and please leave feedback
Sorry for my english
