Configuring Key ForceWare Graphics Driver Features
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.
Multi
‐
Display

Acceleration
settings
determine
advanced
rendering
options
when
using
multiple
displays
and/or
graphics
cards
based
on
different
classes
of
NVIDIA
GPUs.
The
settings
are
shown
in
.
Note:
Multi

hardware
acceleration
options
do
not
apply
when
using
nView
Multiview
mode
in
Windows
NT
4.0.
•
Single
‐
display
mode
:
If
you
have
only
one
active
display,
this
is
the
default
setting.
You
can
also
specify
this
setting
if
you
have
problems
with
the
multi
‐
device
modes.
•
nView
Clone/Span
mode
is
the
default
setting
when
your
nView
display
mode
is
set
to
nView
Clone
mode
or
one
of
the
nView
Span
modes.
If
multiple
NVIDIA
‐
GPU
based
graphics
cards
in
your
system
are
in
use
with
active
displays,
this
setting
is
replaced
by
one
of
the
“multi
‐
display”
modes
described
below.
•
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
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.
Note:
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.
When
this
mode
is
in
effect,
OpenGL
renders
in
“performance”
mode
for
all
