NVIDIA ForceWare Graphics Display Driver — Feature History
•enabling
GL_POLYGON_SMOOTH
no longer forces software rendering, resulting in
much better performance at some cost in visual quality
Direct3D
Release 5 contains the following Direct3D changes:
• accelerated full-scene anti-aliasing is enabled (GeForce, Quadro, GeForce2)
• limited three-stage setup is now possible
•
D3DVTXPCAPS_MATERIALSOURCE7
capability bit is now disabled (leaving the driver
with DirectX 6 material source capabilities)
The following Registry keys are useful for applications that do not blit correctly:
•
FLUSHAFTERBLITENABLE
is a new Registry key that controls the wait-after-blit
condition when the
DDBLT_WAIT
flag is set.
(Default is
DISABLED
—do not wait.)
Note: This Registry key was formerly named
WAITAFTERBLITENABLE.
•
FORCEBLITWAITFLAGENABLE
is a new Registry key that forces the
DDBLT_WAIT
flag to
be set for all blits, which prevents applications that do not check the return value
from unexpectedly losing blits.
(Default is
DISABLED
.)
•
LIMITMAXQUEUEDFBBLITSENABLE
is a new Registry key that limits the maximum
number of queued blits to the front buffer to a value set by the
PRERENDERLIMIT
Registry key, which is 3 by default.
(Default is
DISABLED
.)
Control Panel
NVIDIA now provides Control Panel tabs for Windows NT 4.0 and Windows 2000.
