-
- Notes, Problems, and Limitations
- --------------------------------
-
- - DirectDraw, Direct3D and DirectVideo support
-
- The DirectDraw driver we provide is compatible with DirectX 2 and includes
- Direct3D support. For our DirectDraw/Direct3D driver to be called, and benefit
- from hardware accelerations, Microsoft DirectX 2 MUST be installed, even
- for applications originally made for DirectX 1.
-
- For your convenience we have placed a copy of the Microsoft DirectX 2
- redistributable code on our Web site. If you are getting this driver from a
- Matrox CD-ROM, you will also find a copy of DirectX 2 on the CD.
-
- If you have a Millennium card, the DirectX 2 setup will detect it and print
- the following messages:
-
- "Setup has detected display drivers that have not been tested with
- DirectX. To get the best game performance, Setup can replace your existing
- drivers."
-
- "Replace existing display drivers with DirectX drivers?"
-
- Answer "No" to the question. Otherwise, DirectX 2 would install its
- Millennium display driver which is not as optimized and does not
- support PowerDesk.
-
- Note that the Microsoft DirectX 2 code does not include DirectVideo-enabled
- codecs. Hence for faster playback of Indeo and Cinepak AVI files, you should
- install the Microsoft DirectVideo redistributable files. This package is
- available on our Web site and on our latest CD-ROM.
-
- - Bus Mastering support under Matrox Mystique
-
- The Matrox Mystique supports bus mastering, which can accelerate 3D frame
- rate and video playback in Windows 95. A switch is available in the MGA
- Advanced Settings sheet to enable/disable bus mastering.
-
- Please take note of the following regarding bus mastering in this version:
-
- - bus mastering support is not yet implemented for video playback, hence
- performance will be the same whether the switch is on or off.
-
- - bus mastering support is however implemented in Direct3D and upcoming
- Mystique bundled games.
-
- - some early PCI systems do not properly assign an interrupt to graphics
- boards such as the Mystique. Bus mastering requires an interrupt, so
- failure to get an interrupt will result in 3D applications not using
- this performance feature.
-
- - Adobe Type Manager limitation
-
- When Adobe Type Manager is installed, you cannot run the driver if
- the "Advanced Graphics Acceleration Settings" is set to none. Note
- that ATM is installed as part of Adobe Acrobat Reader. This is an
- Adobe problem documented in the Windows 95 "display.txt" file.
-
- - Monitors in interlaced mode
-
- Some old monitors such as the IBM 8514 and the NEC 3D do not support
- non-interlaced mode in all resolutions. The MGA driver does not
- properly handle interlaced mode under the Windows 95 monitor
- mechanism, so if you own one of these monitors, please use the MGA
- Monitor Program.
-
- - PowerDesk and localized versions of Windows 95
-
- When PowerDesk installs its special settings page in the Windows 95
- Display Properties panel, it should grey-out the normal Microsoft
- "Settings" page. This has been tested under the languages we have
- localized PowerDesk in. With other languages, it may not work. In
- this case, DO NOT USE THE MICROSOFT SETTINGS PAGE. Otherwise, you
- will confuse the MGA display driver, which uses the Windows 95
- "Desktop area" as its VIRTUAL desktop area; rather than changing
- your resolution, you will actually change your virtual desktop.
-
- - DirectDraw and Automatic Power Management
-
- As stated in "Microsoft DirectX release Notes" dated September 30,
- 1995, A DirectDraw game might be unable to restore properly if it
- is suspended by Automatic Power Management utilities.
-
- - VESA modes:
-
- Your MGA Video BIOS supports DOS VESA SuperVGA applications and
- games in the following modes:
