Limitations in This Release
The following are features that are not currently supported or have limited
support in this driver release:
• Refresh Rate Precision
The current driver programs the hardware timing for a 59.94 Hz refresh rate
to be the same as the timing used for a 60 Hz refresh rate.
• Pan & Scan
This driver does not support the Pan & Scan feature. (Pan & Scan is the
process of panning across the desktop in order to display a desktop on a
monitor with lower resolution).
• DirectX Antialiasing
The NVIDIA Control Panel does not offer full antialiasing support for
DirectX applications. NVIDIA Control Panel antialiasing should be set to
Application-controlled to ensure compatibility with all DirectX applications.
• Full-featured HDMI Support
The following are known problems that will be fixed in a future driver
• There are some known image quality issues.
• Noise and pixel corruption occur under Clone or Dualview modes.
• Only stereo audio is supported; 5.1 surround is not supported.
• INF Support for Restricted Timings
This driver version does not support the use of Restricted Timing settings
(R&T strings) in the INF to control mode validation and/or mode setting for
custom mode/adapter/monitor combinations. This capability is planned for
a later driver release.
• Display rotation
The NVIDIA Control Panel does not include display rotation controls.
• Overscan/Underscan Support
The ability to display the entire desktop on a TV is not supported—the
desktop will be masked instead.
• Advanced Timings, Custom Resolutions
This driver does not support adding arbitrary resolutions and timings.
• Mode Filtering for Custom Policies
This driver does not support defining advanced timings and resolution
This driver does not support the Serial Display Interface (a standard for
driving high color depth displays).
• Genlock/Frame Lock
This driver does not support the ability to synchronize multiple display
outputs with an external signal.
• NVIDIA SLI Technology
This release is intended to serve as a functional preview for application
porting purposes, and not as a performance driver.
• NVIDIA TurboCache
The driver is capping Shared System Memory at 255 MB on systems with 1
GB of system memory, and at 271 MB on systems with 2 GB or more of
system memory. An upcoming driver will increase this amount of memory.
Optimum performance will not be achieved with low frame buffer
TurboCache graphics cards.

hmmmm that sounds like some of the bugs that were annoying me. UAC flicker drove me nuts, especially since my Mac's Intel graphics chip could handle Vista better than my Nvidia. Does this mean the kop48 is about to switch to Vista? Only time will tell.Had some flickering in games before, that went. UAC dialog pops up faster and smoother (yes i still run UAC ), smoother windows animations in general. Not noticed any cpu spikes either
