This fix only for bf3 and windows 7 If you have like me been suffering from really bad hitreg ingame lately (clips emptied in enemy to virtually no effect and you see the X's marking the hits but don't make the damage the bullets should, get killed around corners etc) Try this fix.

When i got IP probs i use a netsh command to reset the winsock for example. The dowloaded zip includes instructions, file to execute the setting and file to reset it back to what it was. Hope it will also help others that suffer from the bad hitreg and i'm just sharing this info. It isn't mine but the author of the vid. Thanks belong to ExProsiveGaming ! EDIT : Alternative to sort local network issues (by Samoz): Just gonna use this topic to link TCP optimiser which itself does some of these tweaks depending on you internet speed etc http://www.speedguide.net/downloads.php might help some people Note from Samoz : netsh int tcp set global ecncapability=enabled Just a note to be careful of this tweak as it can lead to not being able to login into some older EA games due to them not supporting ECN EDIT 2 : - Soft Quicktime might not be compatible - Defrag HDD - Restart your router properly.
