When you right click a DOS program (or .PIF) in Explorer and choose Properties, you get the NT 4.0 version of the PIF editor.
- If the application runs in a window and the video performance is slow, try full-screen mode on the Screen tab.
- Disabling the Compatible Timer Hardware feature in the _DEFAULT.PIF or the applications PIF on the Program tab / Windows NT button should only be used if it is required to make the application run.
- If the application runs Windowed and pauses periodically, try disabling Idle Detection on the Misc tab.
- If the DOS application can be configured for printing, choose LPTx. Most DOS apps use Int17 when configured to print to LPTx and print directly to the port.
