Configuring Key ForceWare Graphics Driver Features
SLI Rendering Mode
Note:
SLI rendering mode
settings are available only if you are running in an SLI
multi-GPU configuration (
Figure 7.15
).
Figure 7.15
Advanced Driver Settings Displaying SLI Rendering Modes
•
In
Auto-select
mode, the NVIDIA driver automatically selects the multi-GPU
rendering mode to use.
•
In
Alternate frame rendering (AFR)
mode, consecutive frames are rendered by
two separate groups of GPUs. Each group processes alternating frames and
operates on each frame as in split-frame rendering mode.
•
Alternate frame rendering 2
, which is another version of the AFR mode, may
provide better performance than using the regular AFR mode in certain
applications
•
In
Split-frame rendering
mode, each frame is divided into horizontal strips, with
each GPU responsible for rendering one strip. Line(s) between horizontal strips
are
not visible
for the user.
