PsyScope Files. DmDX help, dmdx. DMDX Help. Last Updated: 11/21/13 j.c.f. This is the help for DMDX version 4, Dmastr for Win32 (Windows 98, 98SE, ME, 2000, XP, Vista and Windows 7) with DirectX 7.0 or later. While DMDX will work with Vista and Windows 7 in addition to your display and audio drivers needing to be good (a long standing feature of DMDX being the ability to expose poor drivers) you should also turn off Desktop Compositing. Windows 8 is actually a bit of a problem and must be run at this time with a special command line override to limit display buffers to 1 (-buffer 1, a special Windows 8 shortcut with this has been added to the DMDX start menu shortcuts). Version 1 worked on 486 class machines, Version 2 of DMDX dropped support for 486 class machines allowing much more accurate timing and generally cleaned up a lot of stuff like multi-monitor support. Please note that we distribute this software as is, with no guarantees as to its reliability.
