4-10 Chapter 4
NOTE: When Multi-Device Compatibility 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-Device Performance Mode: This mode is available if you have two or
more active display devices when running in nView Dualview mode or if you
are using different classes of NVIDIA GPU-based cards.
NOTE: When Multi-Device Performance 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 display devices may result in minor transient rendering artifacts.
 Default color depth [for textures]: This option determines whether textures
of a specific color depth should be used by default in OpenGL applications.
Use desktop color depth will always use textures of the color depth at which
your Windows desktop is currently running. The Always use 16 bpp and
Always use 32 bpp options will force the use of textures of the specified color
depth, regardless of your desktop settings.
 Buffer-flipping mode: This option determines the buffer flipping mode for
full-screen OpenGL applications. You can select from the block transfer
method, the page flip method or auto-select. Auto-select allows the driver to
determine the best method based on your hardware configuration.
 Vertical sync: This option lets you specify how vertical sync is handled in
OpenGL. Always off will always disable vertical sync in all OpenGL
applications. Off by default will keep vertical sync disabled, unless an
application specifically requests that it be enabled. On by default will keep
vertical sync enabled, unless an application specifically requests that it be
disabled.
 Custom OpenGL settings: A list of the custom settings (or “tweaks”) you
have saved. Selecting an item from the list will activate the setting. To apply
the setting, choose the “OK” or “Apply” button.
