| Data type | Range | Default value |
|---|---|---|
REG_DWORD |
Seconds |
7 |
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. |
Changes made to this entry take effect when you change video modes with Display Properties and when you restart the computer.
