I'm having terrible lag. It is NOT my connection for sure. I play BC2, Crysis 2, and dozens more with zero lag but this game is choppy. I also believe it is not my PC as No other game stutters or lags. I'm choosing servers with less than 40 ping also. Any help is appreciated.

My PC is:

AMD Phenom 2 965 BE
Sapphire ATI 5870 VaporX
6 gig Ram
650 GB WD Black Edition HDD

i have almost the same build my processor is a bit overclocked (my usually overclock made this game unhappy --only this game lol--)

I have a vaporx instead with 8gb ddr2 ram and a ssd but the game is on a 7200rpm 2tb. Anywho - i get lag, no sound occasionally, invisible players...I believe these are all BUGS! Hopefully they will release a patch to fix these things. Else they will lose the people that have been waiting for this for the longest time!

This is an Issue with all AMD/ATI cards, the game is unbelievably horrid with these cards and does not even function correctly. FIX THIS IMMEDIATELY

Ya I installed the ATI 11.5a Hotfix that was supposed to fix AMD issues.

The Hotfixes never work my friend.

Hopefully they will have a fix fast. SD is normally pretty good at fixes.
