In late February, I updated my video driver from 179.85 to 186.64. Everything seemed to go smoothly until I realized that while playing, the frame rates 60-19 was significantly reduced, consistent in all areas! When I realized that SLI is enabled when I upgraded the driver and still I was not able to know what was the problem. So I went into the Nvidia control panel, but to disable SLI is gray! I cannot disable it. I can disable PhysX, SLI, but no. Oh, I cannot undo my driver because it is gray and so what should I do? Should I disable one of my video cards from device manager? Do I have to manually reinstall the 179.85 drivers if I can find them? Should I upgrade to new drivers 19X.XX? Please help as I can play World of War craft award and GT raids and I have almost lag and this team has never had this problem since the property.
