S3 Video Performance Improved in Windows NT 4.0 (166772)
The information in this article applies to:
- Microsoft Windows NT Workstation 4.0
- Microsoft Windows NT Server 4.0
This article was previously published under Q166772 SYMPTOMS
Response times on S3 video-based systems are not optimal. Also,
periodically because of the refresh rate, the mouse does not respond as you
expect if mouse move events are requested in quick succession.
CAUSE
For each mouse cursor movement, Windows NT is waiting for a V-refresh.
However, on the current S3 video chipsets, this is no longer required.
RESOLUTION
To resolve this problem, please install the latest Windows NT Service Pack.
This problem is fixed in Windows NT 4.0 Service Pack 3.0 and later.
STATUS
Microsoft has confirmed this to be a problem in Windows NT Server and
Windows NT Workstation version 4.0. This problem has been corrected in the
latest U.S. Service Pack for Windows NT version 4.0. For information on
obtaining the Service Pack, query on the following word in the Microsoft
