Matrox Millenium 4/8mb bug

[WhiteMagicRaven]

What happened?

i found that 2mb millennium is ok, but using 4mb or 8mb causes distortion in image on game Nascar Racing which uses MGA 3D Acceleration capabilities of this video card.

i have 4mb millennium and i tested on real hardware its not happens here.

2mb ok 4mb bug / real hardware ok

8mb bugged also. Can't say how it acts on real hardware, assuming should be also ok.

Since you have a real Millennium card, could you test Duke Nukem 3D to see how it runs when using VESA mode? Under 86Box (4 MB card, 4.12 drivers) it keeps returning the "VESA driver not found/supported error". I also tested Screamer 2 and with Millennium I it ran beautifully in SVGA mode, whereas with Mystique 220 (using the same 4.12 drivers) it was barely playable even in VGA mode on an emulated Pentium II 350.

currently not possible to test, since i moved out, and will arrive few months later, and than will have access to real hardware. Sorry

[unreal9010]

According to Mactar's tests, none of the Matrox cards are having issues with running Duke Nukem 1.3D in VESA mode, except for some screen tearing that apparently occurs with Mystique and the cards that were released after it (strangely, Parhelia, the latest from the bunch, seems to be fine).

[Dudejo]

According to the 3D Realms legacy website, the only issue that should be happening on a Matrox Millenium is a system crash when running Duke 3D in 800x600.

Closing because it's being tracked in #4617 .
