Windows Vista Considerations

These are behaviors that may be different from Windows XP and are related directly to

the Windows Vista operating system.

 Gamma ramps are inconsistent between single and two-headed systems.

 NVIDIA TurboCache

Windows Vista now controls the allocation of system memory to the GPU for

TurboCache functions. The Windows Vista Display Properties pages show the shared

system memory (SSM), or how much memory is allocated for NVIDIA GPUs to use

for TurboCache.

Windows 7 Considerations

Windows DWM Disabled for SLI Mosaic Mode

Due to compatibility issues, when using SLI Mosaic mode the driver turns off the

Windows 7 Desktop Window Manager (DWM). As a result, DWM-managed desktop

features such as Windows Aero or Windows Flip 3D will not be available.

Hotplug Action

Unlike the hotplug activity under Windows Vista, the default settings are not applied

when a new display is hotplugged, and there is no message balloon alert stating that a

new display was detected. Under Windows 7, all display connection and detection

events are handled through the Windows 7 Connecting and Configuring Displays (CCD)

mechanism.
