Use mip-mapping texture calculations
Use mip-mapping texture calculations
If checked, mip-mapping will be used for texture calculation when
requested by an OpenGL application. If disabled, only the largest map
will be used and texture calculations will be done with bi-linear
sampling. Mip-mapping is disabled by default for maximum OpenGL
application performance. Heidi applications are unaffected.
Sync buffer swap to vertical refresh
Sync buffer swap to vertical refresh
If enabled, double buffer swapping occurs during your monitor’s
vertical blank period. Although there is a slight performance loss, this
feature improves the appearance of artifacts by eliminating inter-frame
tearing.
Enable dual monitor mode
Enable dual monitor mode
If two Oxygen 102, two Oxygen 202 or two Oxygen 402 cards are
installed in the system, checking this option enables the use of dual
displays. The cursor will track from one screen to the next. Disabling
this option turns off dual display, even if two cards are present. This
option is grayed out if you do not have two Oxygen cards installed.
Use Alpha
Use Alpha processor optimizations
processor optimizations
If enabled, this feature optimizes operations possible on most Alpha-
processor subsystems. If disabled, compatibility with all Alpha
systems is ensured.
We recommend enabling this feature in order to maximize
performance unless you have a DeskStation Raptor processor. These
users may experience boot problems and should leave this feature
disabled. If your system does not boot after enabling this feature,
reboot and press the
enter the “Last known good boot” menu. Select “Last known good
boot” option by pressing “L” under Windows NT 4.0 or highlighting
that option in the Windows NT 3.51 menu. The option and any other
NT registry changes since the last good boot will then be restored back
to their previous states. You may also contact your hardware
manufacturer for more details.
