Hi, this is the way what I found to play pretty well these games on SLI. No flickering and fix mostly of the stuttering. My rig is detailed in my profile. BATTLEFIELD 4 (update1) 1.- Install NVIDIA drivers 320.49 http://www.nvidia.com/object/win8-win7-winvista-64bit-320.49-whql-driver.html 2.- With nvidiainspector, delete the profile for BF4 and import this one: http://www.mediafire.com/download/dfdn8ydf3fikuya/bf4_fix.nip 3.- Set Physx to CPU in Nvidia control panel. 4.- In game settings, set graphics quality to ultra (even AA post:high and AA deferred:4 msaa), except motion blur (0), dof (off), hud size (30) and resolution scale (100). 5.- Copy this "user.cfg" to the BF4 directory: http://www.mediafire.com/download/5fc7nz8q9x9cf49/user.cfg 6..- Play COD:GHOST (update 1) 1.- Install NVIDIA Drivers 331.65 http://www.nvidia.com/download/driverResults.aspx/68799/en-us 2.- With nvidiainspector, delete the profile for COD:GHOST and import this one: http://www.mediafire.com/download/sl881aj50q58iws/ghost_fix.nip 3.- Set Physx to CPU in Nvidia control panel 4.- For windows 8.1, install this update http://support.microsoft.com/kb/2908279 5.- Copy this "config.cfg" to the directory "COD:GHOST > players2".

If it is not your native resolution, you must change it: turn off "only read" attribute, edit with notepad, save and turn on "only read" attribute after the changes. http://www.mediafire.com/download/6u29223pvhw2adq/config.cfg 6.- Play.
