GLYDER MAX-2 WINDOWS NT 4.0 DISLPAY PROPERTIES SETTINGS 
-------------------------------------------------------

GLyder MAX-2 specific variables can be changed in the desktop display settings panel.  This can 
be found by right clicking on the desktop and choosing "Properties".  Then click on the 3Dlabs tab 
to access these settings.

This section describes each of the settings in detail.

FORCE NEAREST NEIGHBOR FILTERING
Setting this check box will ensure that OpenGL only performs nearest neighbor texturing 
operations.  In some applications this can improve performance, at the cost of some visual quality.

ENABLE TEXTURE COMPRESSION
Setting this check box will force OpenGL to shrink 2D texture maps as they are loaded to reduce 
the memory needed to store them. Texture maps are halved in both x and y dimensions so that 
they require a quarter of the original memory. The setting has no effect on 1D or paletted texture 
maps. 

USE HIGH QUALITY TEXTURE MAPPING
This applies only to the GLINT 300SX-based original GLyder product. It is grayed out for other 
products.

FORCE HARDWARE TEXTURING
This variable is only relevant to the GLINT 500TX-based GLyder/TX and GLyder/MP products. It is 
grayed for other products.

PERSPECTIVE CORRECTION
This variable is only relevant to PERMEDIA. The accuracy of the perspective-correction divide 
performed during textured rendering can be varied on PERMEDIA. The default option, Force Nicest, 
enforces the most accurate divide, resulting in the best image quality. The Force Fastest option 
switches to a reduced accuracy divide, which results in best performance at the cost of lower 
image quality. The third option gives control of the divide accuracy to OpenGL applications through 
the API function glHint. A smart application can vary the divide accuracy used on a per primitive 
basis, since primitives that are heavily "perspected" require higher accuracy for good image quality 
than those that are not. 

DISABLE FAST CLEAR PLANES
This applies only to GLINT 300SX, 500TX, and GLINT MX-based products. It is grayed for other 
products.

DISABLE DELTA
This applies only to GLINT 300SX, 500TX, and GLINT MX-based products. It is grayed for other 
products.

DRAW LINE ENDPOINTS
This option when set can improve the legibility of text rendered by some applications using stroke 
fonts, such as Pro/ENGINEER. 

SYNC DBLBUFFER WITH VBLANK
Smooth animation of 3d applications can be achieved by rendering to an off-screen 
window/desktop sized color buffer and copying or swapping the contents to the displayable 
front buffer at the completion of each frame. Enabling this option prevents tearing of the display 
by synchronizing the swap of the back and front buffers to the vertical blank retrace interval of 
the monitor display.

Leave this option unchecked if the highest rendering frame rates of a double buffered application 
are desired (i.e. not locked to sub-multiples of the current display refresh rate).

EXPORT HIGH-RESOLUTION SINGLE BUFFER FORMATS
When this box is checked, it will enable the driver to boot at resolutions where only single 
buffered pixel formats are supported by hardware acceleration (because at higher resolutions, 
there is not enough video memory to support double buffered formats).  By default, this is not 
enabled and it prevents users from booting into a mode that will result in unaccelerated OpenGL 
applications that use double buffered modes. This option should be selected by users wishing to
run 2D applications at the highest available resolutions and color depths, and should be unchecked 
to force the card to boot only into 3D-accelerated modes.

GAMMA VALUE
The gamma correction adjustment affects the entire screen display. The default gamma value is 
1.0 and the allowable range of floating point values is 0.3 to 4.0. Any new user-defined value will 
take effect when the Apply or OK button are selected.


BOOT OPTIONS
------------

These options are accessed by clicking on the Boot Options button in the 3Dlabs property tab, 
within the Display Properties applet.

Number of DMA Buffers
This defines the number of DMA buffers configured for use by the 3D extension. As each 3D 
context is created a DMA buffer will be allocated to it. Typically, each 3D application 
(whether OpenGL or another accelerated 3D API) will use a single context. If all DMA buffers 
have been allocated then shared memory buffers are used instead. If this variable does not exist 
or its value is set to zero then use of DMA is disabled. DMA will not be available if the installed 
GLINT board does not support DMA transfers. In this case an event is logged in the system log 
file. This can be viewed using the Event Viewer. The installation default is 3.

NUMBER OF SUB-BUFFERS
This variable describes the number of sections into which a single DMA buffer is divided for use 
by a 3D application. This is used by interrupt driven DMA to construct a queue of buffers which 
are to be loaded into GLINT by the DMA interrupt handler. The maximum size of the queue is 
always 2 less than the number of sub-buffers specified. This is to allow the 3D application to fill 
one buffer and GLINT to be performing DMA on another buffer. The remainder can be queued.

Setting this variable to 2 disables interrupt driven DMA since not enough buffers are available to 
create a DMA queue. DMA still works but the DMA buffer is split into two parts so that GLINT can 
load one while the 3D application prepares the other. Setting this variable to zero disables DMA 
and forces FIFOs to be used. This latter feature is generally used only for comparing performance 
of DMA and non-DMA operation (without needing a reboot).

This variable is read every time a 3D context is created. Thus it is not necessary to reboot the 
machine for a change to take effect. Changing this variable has no effect on any already running 
3D applications. The installation default is 5.

This variable can have considerable 3D performance implications. 2 is usually ideal for 
single-buffered applications and 5 seems well suited to double-buffered applications. 

SIZE OF DMA BUFFERS (KB)
This variable defines the size in bytes of each DMA buffer. Its value will be rounded up to the 
next system page boundary. The size will be limited to 256KB since this is the maximum size that 
can be specified to GLINT for a DMA transfer. The installation default is 0x10000 (64KB). The 
machine must be rebooted for a change in this variable to take effect.

USE BIOS PCI BASE ADDRESSES
Normally, the NT HAL allocates PCI base addresses for the GLINT card. These O/S-assigned 
addresses override those which are normally supplied by the PCI BIOS. On some machine 
configurations these addresses are not valid for the given hardware. In these instances, the 
base addresses originally configured by the BIOS are often valid and allow the machine to boot. 
Checking this box causes the BIOS base addresses to be used rather than those configured by 
NT.

In particular, on machines which use the Intel Multi Processor Specification 1.4 (MPS 1.4), there is 
a bug in the NT HAL for many machines which causes invalid base addresses to be configured. 
Setting this variable may fix this problem. This box is checked by default.

DISABLE PCI DISCONNECT
Higher 2D graphics performance can be achieved by using PCI Disconnect, however this feature 
can sometimes adversely affect the performance of other devices, such as modems and sound 
cards. 

Check this option if you are experiencing problems with the performance of other devices. 

For further information on this option, see the topic Optimizing Performance below

EXPORT 'PFD_SUPPORT_GDI' IN SINGLE BUFFER FORMATS
EXPORT 'PFD_SUPPORT_GDI' IN DOUBLE BUFFER FORMATS
These two check-boxes control whether the  PFD_SUPPORT_GDI flags are exported for single 
buffered and double buffered pixel formats. The default is checked for both.

SOFTIMAGE VERSION 3.01 SPECIFIC SUPPORT
Version 3.01 of SoftImage requires this to be checked to ensure the correct operation of 
SoftImage  on GLINT 300SX, 500TX, and MX-based boards. This option is grayed for other 
products.

SOFTIMAGE VERSION 3.51/3.7 SPECIFIC SUPPORT
Versions 3.51 and 3.7 of SoftImage require this to be checked to ensure the correct operation of 
SoftImage  on GLINT 300SX, 500TX, and MX-based boards. This option is grayed for other 
products.


OPTIMIZING PERFORMANCE
----------------------------------
In the Control Panel / Display applet, under the Symmetric tab, the setting
of "Disable PCI Disconnect" is selected (checked) by default. When this option is checked,
100% compatibility with all serial ports and sound cards are guaranteed. Clearing the 
checkbox for this option will give a 5%-10% performance increase, but may cause data corruption
in some serial port or sound card peripherals.
