I previously had a gtx 275 card that ran BF fine on low but I wanted to upgrade to get High or Ultra. I removed the Nvidia drivers and installed the new card. Added the drivers from the CD then updated to the newest drivers.
ISSUE: during game play it becomes laggy. When running then stopping the screen keeps moving forward then jumps back. Using a scope is impossible because of lag and flying anything is out of the question.
The game sometime freezes and I have to ctrl+alt+del to close the frozen screen.
Moved video card to other slot and changed the power plugs to the other two empties. It seems to be running smooth now. One thing is that I dont have the sound plugged back in yet. I'm hooking everything back up and will test once more.
If you're using the 12.1 drivers, try the 11.12. I was also using the 12.1 drivers and the game was unstable, kept crashing, etc. reinstalled drivers multiple times nothing would fix it (be sure to run Driver Sweeper or similar in safemode after the uninstall)
Went back to 11.12 and everythings working as it should.
