I see that a lot of ppl are still having issues with the game (crashes, rubberbanding, disconnections etc etc). I resolved most of my problem, now the game is stable and i only get disconnected if the whole server that i'm playing in, crash, or if an admin log in with a reserved slot .
Here's a complete and detailed list with things you can try in order to completely fix your battlefield:
The game ALWAYS crash after 2-5 minutes/pc reboot itself after 2-5 minutes.
-Reboot your computer, open the bios (by spamming del on your keyboard)
-Get to the motherboard configuration-north bridge configuration
-Disable HD audio. if it's enabled, you simply press + till it says is disabled.
by doing this, your PC audio will be completely disabled unless you have an audio card or an USB headset or something similiar (usb).
To re-enable audio, simply get back to the settings and enable HD audio again.
The game crash randomly after about 15/20 minutes.
-Press start (or the windows logo)
-Type in the searchbar "cmd" without the "
-a command windows should open up. write "bcdedit /set increaseUserVa 3072" without the "
Case 1: operation concluded succesfully (or a similiar message)
Case 2: you are not allowed to do that (or a similiar message)
-Press start again
-Click "all programs"
-RIGHT click "command prompt" and click "Run As Admin"
-Type in the command windows "bcdedit /set increaseUserVa 3072" as always without the "
This will fix the problem, wich is caused by memory leak
Get disconnected very often without a reason.
-Download PBsetup from here: PunkBuster Online Countermeasures
-Extract the files in a folder
-Click "add a game"
-Select "Battlefield 3". The path of the game should be detected automatically, if not, point it to the right path.
-Click check for updates
-Once the downloads are over, you'll get a message "battlefield 3 is up to date" or similiar. you may now close the application.
-Click on the windows logo/start button
-In the searchbar, type services.msc
-A list of services should now be in front of you.
-Click "extended" tab
-Search for "UPnP host devices" or something similiar (the description is something like: Allow hosting of UPnP devices blablabla)
-Right click it
-I don't know how to translate this, but there is an option like "startup", in the general tab. You can choose between: Automatic (delayed startup), Automatic, Manually, Disabled. You must choose Disabled.
-Click on "stop service"
-Click "apply" and close that little windows.
-Search for "SSPD discovery" and do the same things that you did above.
-Type in the adress bar 192.168.0.1 and press enter. if nothing work with that IP, try with one of these: 192.168.1.1, 127.0.0.1, 127.0.1.1. With one of these IPs you should be able to open up your router's page.
-Log into the router panel (username is usually "admin" or "administrator", aswell as the password)
-Once you are in, you should search for an option called UPnP, and disable it. it might be somewhere in the advanced options, i really can't help you with this one because it's not on my router, and every router it's different, so you might or might not have it.
In case you still have the problem...well...go to the nearest churc and turn on a candle, then prey for a bit.
EXTREME rubberbanding, mostly in Caspian Borders, Teheran Highway and Grand Bazhaar.
-Reboot your computer
-Spam DEL till you open the biones panel again
-Search for advanced options
-Look for an option named "HTT" or "Hyper Treading" or "Hyper Treading Technology" and press + till it's disabled.
-Save and exit
I know this might look strange, but it fixed me, and 5 other friends, the rubberbanding issue (different cpu's, 4 intel and 2 amd).
You will still notice some rubberbanding if the server is lagging.
edit: no idead what to do with the amd, since i've been reported that htt it's just for intel :> i guess the 2 amd guys didn't have the problem in the first place or disabled another tech, i'll ask them and report here
The screen goes black and the game crashes everytime i try to join a server
This happened me yesterday too, basically i was playing CQ64 on metro, and the game crashed (probably god punishment or karma :P). After that, i tried to rejoin on metro like 5/6 times, everytime the game was not loading at all, and eventually crashing during the map loading:
-Join a server with a different map, this will eventually restore the whole game (worked for me)
-Run a repair from Origin (right click battlefield 3 on origin, and click reapair)
ALL THE SOLUTION WROTE ABOVE ARE REVERSIBLE, SO FEEL FREE TO TEST OUT EVERYTHING, IT MIGHT HELP YOU.
