I have three of these monitors all connected to a single GTX 680. The center monitor is connected via HDMI and the two side monitors are connected via DVI. With only a single monitor enabled, there is no lag. When I enable a secondary or third monitor in Control Panel>Display>Extend desktop to this display, I get lag. FireFox scrolls unsmoothly and animations throughout Windows are sluggish. I have Minecraft opened on the center monitor. The ingame FPS counter always stays above 80 but "feels" like 40 FPS (it's not smooth). Any suggestions on what to do?

Enabling the secondary and third monitors with NVIDIA's Control Panel (Surround) doesn't give any lag but breaks window snapping so I'd really like to control the monitors with Windows Control Panel.

NVIDIA Control Panel


Looking at the above....it seems to me that you would like Windows Control Panel to have properties that are specifically provided by the NVIDIA tool.  I don't see how that can happen but I'm not very clever about these things.  As I understand it, Windows Control Panel is designed to provide basic functionality, not extraordinary capabilities inherent in the driver/support packages for hardware.
