Data type

Range

Default value

REG_DWORD

Seconds

7

Description

Specifies how long a DirectDraw application can keep a graphics-device frame-buffer locked while a dynamic-mode or security-desktop change is pending.

When the time specified in the value of this entry expires, the system requires the DirectDraw application to release the frame buffer. Requiring the release prevents the DirectDraw application from locking and thus not releasing its resources. However, requiring the release might cause an access violation error.

Value

Meaning

0

DirectDraw acceleration is disabled and direct frame-buffer access is not permitted. However, DirectDraw continues to run in emulation mode.

Seconds

The number of seconds the system waits before requiring a DirectDraw application to release a frame buffer.
