TITLE   :World Tour Tennis Fails to Run on Windows NT
PRODUCT :Windows NT
PROD/VER:3.10
OPER/SYS:WINDOWS
KEYWORDS:

----------------------------------------------------------------------
The information in this article applies to:
 
 - Microsoft Windows NT operating system, version 3.1
 - Microsoft Windows NT Advanced Server, version 3.1
----------------------------------------------------------------------
 
SYMPTOMS
========
 
World Tour Tennis (an MS-DOS - based game) may fail to run on Windows
NT.
 
CAUSE
=====
 
The World Tour Tennis sound generation algorithm increases the timer
hardware tic rate by 11kHz. The overhead required for Windows NT
virtual DOS machine (VDM) to generate and service the timer interrupts
(to emulate this very high tic rate) causes World Tour Tennis to
constantly service the timer tics. As a result, World Tour Tennis
appears to stop responding (hang).
 
RESOLUTION
==========
 
To work around this problem:
 
 - Turn off sound in World Tour Tennis.
 
   or
 
 - Create a .PIF file for World Tour Tennis which has Compatible Timer
   Hardware Emulation enabled.
