(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.

NVIDIA Driver Feature History
•
GL_WGL_swap_interval
extension can change Vsync behavior.
•
Vsync is on by default. (Default behavior is selectable from the NVIDIA
OpenGL properties tab.)
•
Default anisotropic filtering can be triggered by checking the anisotropic
filtering box on the NVIDIA OpenGL properties tab.
•
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 antialiasing is enabled (GeForce, 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
.)
