Using NVIDIA SLI Technology

This section explains how to use the following SLI features:
• SLI Frame Rendering
• SLI Antialiasing Mode
• SLI Single‐GPU Mode
• Using the 3D App Profiles
• Viewing Load Balancing

SLI Frame Rendering

SLI frame rendering accelerates OpenGL operation in two different ways:
• Split frame rendering: In split‐frame rendering (SFR), the display is split into
distinct sections, and each section is sent to a different GPU. The resulting
rendering is recomposed and displayed as a single contiguous frame. The position
of the split is adjusted dynamically as the workload moves between the GPUs. SFR
typically benefits pixel‐shader or texture‐intensive operations
• Alternate frame rendering: In alternate frame rendering (AFR), each GPU renders
alternate frames of data from the application. AFR typically benefits geometry‐
intensive operations
To use SLI frame rendering, perform the following steps:
1 Open the Performance & Quality Settings page.
2 From the Active profile list, select Global driver settings.
3 From the Global driver settings View list, select Advanced settings.
4 From the Global driver settings list box, select SLI rendering.
5 Click the When SLI is enabled, use list arrow, click one of the following SLI
rendering modes, then click Apply:
• Split frame rendering
• Alternate frame rendering
• Alternate frame rendering 2
Alternate frame rendering 2 is an alternate version of AFR that may provide
better performance than AFR 1 on some applications
