- Microsoft Windows NT Advanced Server, version 3.1
- Microsoft Windows NT Server version 4.0
- Microsoft Windows NT Workstation version 4.0
If you are not satisfied with the performance of your MS-DOS-based
applications on Windows NT, try the following:
Windows NT 4.0 keeps the same setting in the property (right click) of
the MS-DOS-based applications.
- If the application is in a window and the video display performance
is slow, try full-screen mode. Windows NT 4.0 �screen folder� provides
this setting.
- Disable the Compatible Timer Hardware feature in the _DEFAULT.PIF or
the application's program information file (PIF) under the
NT-specific section of PIF Editor. Since this feature causes a
decrease in performance, it should be used only if it is required to
make an application to run with Windows NT. Windows NT �program folder�
under �Windows NT� section provides this setting.
- If the application is in a window and seems to pause periodically,
try disabling Idle Detection in the Advance section of that
application's PIF. Windows NT �misc folder� provides this setting
in a form of a slider bar called �idle sensitivity�.
- If the MS-DOS-based application can be configured for printing,
choose LPT1, LPT2 over parallel port. Most of the applications use
Int17 to print when configured for LPT<x>. If you select parallel port
mode, these applications print directly to printer ports. Parallel
mode is significantly slower in Windows NT compared to Windows 3.1.
