Chapter 9
Using NVIDIA Scalable Link Interface (SLI)
The resulting SLI modes are listed in Table 9.1.
See the next sections for detailed steps on using these modes.
SLI Frame Rendering
To use SLI frame rendering, perform the following steps:
1 Enable SLI multi-GPU rendering
a Open the Performance & Quality Settings page.
b From the Active profile list, select Global driver settings.
c From the Global driver settings View list, select Advanced settings.
d From the Global driver settings list box, select SLI rendering and then choose
SLI multi-GPU rendering.
e Click Apply.
2 Choose the frame rendering mode.
SFR typically benefits pixel-shader or texture-intensive operations, whereas AFR
benefits geometry-intensive operations.
• To select AFR, select 3D App-Modeling AFR from the Active profile list, then
click Apply.
• To select SFR, select 3D App-Visual Simulation from the Active profile list,
then click Apply.
This profile is also useful for non-SLI configurations, since it optimizes the
driver for texture- and shader-intensive operations.
