Configuring Key ForceWare Graphics Driver Features
•
Multi-display compatibility mode
is available if you have two or more active
displays when running in nView Dualview display mode or if you are using
different classes of NVIDIA GPU-based graphics cards.
Note:
When this mode is in effect, OpenGL renders in “compatibility” mode for all
displays. In this mode, when different classes of GPUs are in use, the lowest
common feature set of all active GPUs is exposed to OpenGL applications.
The OpenGL rendering performance is slightly slower than in single-
display mode.
•
Multi-display performance mode
is available if you have two or more active
displays when running in nView Dualview mode or if you are using different
classes of NVIDIA GPU-based cards.
Note:
When this mode is in effect, OpenGL renders in “performance” mode for all
displays. As in “compatibility” mode, when different classes of GPUs are in
use, the lowest common feature set of all active GPUs is exposed to OpenGL
applications. However, the rendering performance is “faster” than in
compatibility mode, although switching or spanning displays may result in
minor transient rendering artifacts.
Trilinear Optimization
This option enable you to have full control over trilinear optimizations in Direct3D
and OpenGL applications.
1
Make sure the
View advanced settings
option is selected from the View list.
2
Select
Trilinear optimization
from the driver settings list. The available slider
settings are
On
and

allows better texture filtering performance with no perceived loss of image
quality. You can view the areas of the image that are affected by the trilinear
optimization by enabling textures that contain colored mipmap chains that are
used in typical diagnostic applications. Also see

disables trilinear optimizations and will result in the best image quality.
