Are Windows 95, 98, ME or NT4 supported?

From Version 4.0 onwards, PerformanceTest no longer supports Windows 95 and Windows NT4. From V6.1 build 1002 (May 2007) onwards, support for Windows 98 and ME was also dropped.

Some older, unsupported versions of the software are available for download at the bottom of the download page. If you are using Windows 2000 or Windows 98 but don't have DirectX 9, it can be downloaded from the Microsoft web site.
