You must set the environment variable
SI_OVERLAY=USE_ONE_BIT since Oxygen drivers are
optimized for this setting. In this mode, one bit will be used to display
an overlay plane. Softimage may attempt to put more than one bit of
overlays into the overlay plane if the SI_OVERLAY variable is not set.
Setting this variable can be accomplished in the System Control Panel.
On the Memory Options page in the Oxygen control panel, enable the
“ Increased Z-buffer precision” option for Z-buffer (102 users should
enable the “16-bit Z-buffer” option); the “Optimize for performance”
option for Texture Memory; the “ Alpha buffer” and “Stencil buffer”
options for Dynamic Allocation .
Disable the “ Use mip-mapping for texture calculations” option on the
Advanced Options page in the Oxygen control panel. Softimage|3D does
not use mip-mapping and this will speed up texture loads.
At 1280x1024 resolution, Oxygen 202 users should use 16-bit color for
optimal performance.
