I am on the latest patch as I wanted to play online.. but the lag stops me from playing competativly.
Things I have tried -
Turned off Vsync
Turned off Triplebuffer
Turned off AA
Turned off SLI
Turned off PhysX
Force 75Hz refresh rate (My normal)
Changed Drivers from 178.15 to 180.42
Set OCs to Stock
Disabled Post Processing
Changed SLI mode, AFR1,AFR2 etc.
Stuck... My HD 3600 runs it better!
