Known Product Limitations
Video Playback in nView Clone and Span Modes
 Problem
With nView Clone or Span mode enabled, video playback appears on only one
display under the following conditions:
• Under nView Clone mode, when full-screen video mirror is not used.
• Under nView Span mode, when full-screen video mirror is not used and the video
is positioned to span across both monitors.
 Explanation
With applications that render using the hardware overlay—such as DirectX
applications—the default driver behavior is to enable the hardware overlay when
nView Clone or Span mode is enabled.
Because the driver supports only one hardware overlay, the video appears on only one display.
No Antialiasing of 3DMark03 Image Quality Screen Captures
 Problem
After enabling antialiasing from the NVIDIA Properties page, 3DMark03 screen
captures—obtained using the application’s screen capture function—might not be
antialiased.
 Explanation
This is not an NVIDIA bug, but rather a result of different methods used to render
antialiased images.
Depending on a combination of factors, the driver may take advantage of the NVIDIA
hardware’s ability to bypass the front buffer while rendering an antialiased image. In
this case, the front buffer does not contain antialiased data, so if an application takes
data from the front buffer—as is the case with 3DMark03’s Image Quality screen
captures—then the resulting image is not antialiased.
To accommodate applications that request use of the front buffer, the NVIDIA
software can provide the antialiased data in a buffer to the application. Since this
negates the advantages of the NVIDIA hardware capability, this support is enabled
only when antialiasing is enabled within the application, and not from the NVIDIA
control panel.
In all cases when antialiasing is enabled, screen images as well as screen captures obtained
using the Print Screen key are always antialiased.
