Non moi mon problème était le retour sous windows, le crash en gros mais sur mon lien, je crois avoir vu qu'il propose une solution pour les gens qui ont un problème avec le multi :
Problem #12: When playing Bioshock 2 PC multiplayer online, matches are often laggy — lots of lag
Possible Solution #1: (By EVOL from the Steam forums)
I went poking around for some .cfg or .ini files to see if there might be some settings to control the lag on Bioshock 2, which at least for me, has made the multiplayer completely unplayable.
Check out
%userprofile%\AppData\Roaming\Bioshock2\Bioshock2M
P.ini
That’s the location in Windows 7. For XP, there probably won’t be a “Roaming” folder, so it’d be:
%userprofile%\AppData\Bioshock2
Also, %userprofile% is an environment variable in windows. If you just click start > run, and type in %userprofile% and hit enter, it will pull up your user folder. For XP it’s usually c:\documents and settings\[username], and for Windows 7 it’s c:\users\[username].
Find the line that says
mQuickmatchSearchMaxPing=300
And change the 300 to 100 or less. I’m using 75. Now when I play online, I seem to be pulling lobbies and hosts that I actually have at least halfway decent connections to.
This other variable might be interesting as well:
mMatchSearchPingWeight=0.5
Though I’m not sure if I would want to change it up or down. 0.5 is the default, and I haven’t messed with it yet. If I figure out which direction I want to go, I’d probably move it to 0.2 or 0.8 (whichever is the right direction). It might be linked to:
mMatchSearchSkillWeight=0.5
Perhaps the values between the 2 variable have to add up to 1.0, not sure
Je pense néanmoins que les autres solutions proposés sur le site donné sur mon lien peuvent aussi t'être d'une grande aide !
