Not sure you all want to hear this, but other than TS3 related oddities (having to force close installhook.exe in Task manager before the game will launch and TS muting the sound but then not returning it to the previous level, then reduces the sound again the next time someone talks meaning it's at zero volume) I've had very few problems. I occasionally get a 'BF3 has stopped responding' error on launch but I played for a solid 3 hours tonight, took a break then played
this game (BF3 name is Tesslacoil) and didn't have a stutter or lag at all all evening AND I play wirelessly! I use onboard sound (some Realtek chip, whatever's in my motherboard) and the latest Nvidia driver. I haven't even disabled uPNP on my Router and my video card has a slight overclock but still runs stock volts. I think I have had a freeze during play once or twice throughout the whole time since I started playing but other than that, both pre and post patch it's been great for me. I really can't get my head around the problems loads of people seem to have.
