When running through OpenGL, 3D Studio MAX
®
2 defaults to not backface
culling wireframe objects. This means that wireframe objects typically use twice
as many lines as they do through a Heidi driver. This can result in poor
performance, in comparision to a Heidi driver. This behavior can be changed
from within the application. Go to the File/Preferences dialog box. Click the
Viewports tab and then click Configure Driver. Select the option Display
Wireframe Objects Using Triangle Strips. This causes wireframe objects to
be backfaced culled and can drastically improve performance. The setting also
causes shared edges within polygons to be drawn which may not appear as desired.
The ASUS Display Driver registers a number of event log errors and warnings
when problems are encountered. The events that can be logged include:
•
No DMA support has been configured
•
No interrupt driven DMA has been configured
•
A non-cache coherent PCI bus has been detected which results in uncached
DMA buffers.
•
Fewer than the required number of DMA buffers have been allocated.
After booting the driver, it is advisable to check the system event log to determine
the characteristics of your machine. For example, if an event log indicates that
interrupt driven DMA has not been configured, this may be because the BIOS
has not been configured for PCI interrupts.
To view the system event log, run the Event Viewer from the Administrative
Tools program group. From the Log menu ensure that the System Log has
been selected. Look for events with the Source type glint. Double click on
these events to read the event message.
If no GLINT events are logged, then everything is working perfectly. In this
case, interrupts are working, all DMA buffers have been allocated and the PCI
bus is cache coherent.
